During last decades, titania photocatalysis opened a promising method for Amoxicillin (AMX) abatement in aqueous solution. However, using a photocatalytic powder creates by itself a source of a new pollution. We report on the use of the supported titania nano-photocatalyst in a pilot solar reactor for AMX removal in aqueous solutions. Titanium oxo-alkoxy nanoparticles were prepared in a sol-gel micromixing reactor and coated on a 5-mm diameter borosilicate glass beads. Further heat treatment resulted in anatase coatings of 8 nm thickness. About 450 g of the beads were placed in a main tube of a photocatalytic pilot solar reactor of 150 cm length and 5 cm diameter. Aqueous solutions of AMX 10 mg/L in distilled water were prepared and submitted to the solar tests. Thereafter, pH of the solution was adjusted at 3.5, 7.5 and 9.5 using H2SO4 and NaOH. The total duration of one run was 240 min and the accumulated UV energy was about 35 kJuv/L of solution depending on time of day. The obtained results showed that AMX degradation reaches 76% after 240 min exposure for pH 9.5 and 60% for pH 7.5. The photocatalytic reactor yield remained unchanged after 6 cycles of 240 min treatment; no appreciable deactivation and/or degradation of the nano-photocatalyst were observed. An addition of H2O2 did not appreciably affect AMX degradation. A comparison with the commercial TiO2 powder was carried out in similar experimental conditions and solar exposure in parallel run mode; it showed the higher energetic efficiency of the supported nanocatalyst. IntroductionWater is essential to life on earth and human health. Emerging pollutants including antibiotics have been observed in surface water, ground water, sewage effluent and even in drinking water ADDIN EN.CITE <EndNote><Cite><Author>Ayodele</Author><Year>2012</Year><RecNum>7</RecNum><DisplayText>(Ayodele et al., 2012, Trovó et al., 2008)</DisplayText><record><rec-number>7</rec-number><foreign-keys><key app="EN" db-id="5x05t522pe9fs8ew9pgpfe5yewdef5x9s99w">7</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Ayodele, OB</author><author>Lim, JK</author><author>Hameed, BH</author></authors></contributors><titles><title>Pillared montmorillonite supported ferric oxalate as heterogeneous photo-Fenton catalyst for degradation of amoxicillin</title><secondary-title>Applied Catalysis A: General</secondary-title></titles><periodical><full-title>Applied Catalysis A: General</full-title></periodical><pages>301-309</pages><volume>413</volume><dates><year>2012</year></dates><isbn>0926-860X</isbn><urls></urls></record></Cite><Cite><Author>Trovó</Author><Year>2008</Year><RecNum>11</RecNum><record><rec-number>11</rec-number><foreign-keys><key app="EN" db-id="5x05t522pe9fs8ew9pgpfe5yewdef5x9s99w">11</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Trovó, Alam Gustavo</author><author>Melo, Silene Alessandra Santos</author><author>Nogueira, Raquel Fernandes Pupo</author></authors></contributors><titles><title>Photodegradation of the pharmaceuticals amoxicillin, bezafibrate and paracetamol by the photo-Fenton process—application to sewage treatment plant effluent</title><secondary-title>Journal of Photochemistry and Photobiology A: Chemistry</secondary-title></titles><periodical><full-title>Journal of Photochemistry and Photobiology A: Chemistry</full-title></periodical><pages>215-220</pages><volume>198</volume><number>2</number><dates><year>2008</year></dates><isbn>1010-6030</isbn><urls></urls></record></Cite></EndNote>(Ayodele et al., 2012, Trovó et al., 2008).

It is well established that western countries are the principal PPCPs consumers with 70% of the market compared with other areas of the Globe. However, due to the high costs the conventional waste water treatment is not commonly employed in Asia and Africa, where PPCPs in rivers reaches high concentrations: e.g. 1.49 ng/L of antibiotics against 0.53 ng/L in western countries. Thus low cost and eco-friendly sustainable alternatives are yet to be developed in order to reduce the environmental pollution. The solar heterogeneous photocatalytic detoxification process consists in utilizing the near-UV part of the solar spectrum to photoexcite a semiconductor catalyst in the presence of oxygen. In these circumstances oxidizing species, either bound hydroxyl radical (?OH) or free holes, which attack oxidizable contaminants, are generated producing a progressive breaking of molecules yielding to CO2, H2O and dilute inorganic acids PEVuZE5vdGU+PENpdGU+PEF1dGhvcj5QZXJlaXJhPC9BdXRob3I+PFllYXI+MjAxNDwvWWVhcj48

If many studies have been carried out under UV light however few works demonstrated the photocatalytic degradation of Amoxicillin under natural sunlight in a pilot reactor by TiO2 fixed on the surface of glass beads. The method using TiO2 powder has the inconvenient of dispersing TiO2 in the natural streams leading to a new pollution specifically at nanometric scale and the additional cost of the lost TiO2. In this paper we’ll present the experimental results of degradation of Amoxicillin carried out on nanoparticles of TiO2 elaborated and fixed on the surface of 5mm glass beads by sol gel method. Addition of zirconium atoms to the lattice of TiO2 is expected to modify the band gap and therefor the photochemical activity of TiO2.

The nitrogen pressure of 4 bar were used for applying to mix (A) and (B) solutions at T-mixer in order to reach the Reynold’s number Re ≈ 6000. The micro-mixing reactor is made up of the metal tube having the inner diameter of 1 mm for the input arms joining the tanks (A) and (B) to a an output metal tube of 2 mm in diameter. This permits to develop vortex when the two liquids meet together fast and thus leading to produce nano-metric TiO2 particles. The mixed fluid flow rate was about 10 m/s, which is believed faster than the nucleation and growing phenomena, with control temperature at 20 °C by a thermo-cryostat Haake, DC10K15.

Then they were dried in the oven (at 80 °C around overnight). After the obtained colloidal solutions had been mixed by micromixing reactor and transferred into glove box, these dried borosilicate glass beads were coated during 10 min with these nanoparticles. The coated beads were filtered with filter papers and dried at temperature around 70 °C.The different treatment temperatures were chosen due to different crystalline temperatures of the material and referred to the optimum calcinations for enhanced photocatalytic activity of ethylene photodegradation in gas phase. The film coated pure oxo-TiO2 on borosilicate beads were treated at 450 °C in 4 hours, but at 500 °C for Zr0.05Ti0.95O2. Photocatalytic EvaluationThe Solar photocatalytic experiments were carried out in a pilot plant with CPCs installed at the solar site in the Chemical Engineering Department of faculty of Engineering, university of Isfahan, Iran. The solar reactor consisted of a CPC unit of 4 borosilicate glass tubes arranged horizontally and connected in series by polypropylene junctions with their reflectors covered by polished aluminium. The bottom of one of the borosilicate tubes was lined with the glass beads (453 g = 3113 pieces) covered with TiO2 catalyst. Transmissivity of low iron glass tubes and beads is about 90% for irradiations wavelength between 380 nm and 2000 nm. The pilot plant is fixed and tilted at the local latitude (33°) in order to receive perpendicularly the sunlight. Figure 1: The Solar reactor CPC unit of 4 borosilicate glass tubes equipped with tanks and pumps for recirculation of AMX solutions.Amoxicillin AMX (Mw: 365.4) was purchased from ZHUHAI (China). Lots of 10 L distilled water containing 10mg AMX, used as pollutant molecule, were prepared and put in the solar reactor’s tanks. The pH of solution was adjusted by H2SO4 and NaOH (Merck). The AMX solution was pumped directly from the tank then passed through the tubes arranged in series and submitted to solar irradiation before returning to the tank. This solution was recycled several times during four hours at a rate of 20 L/min. The accumulated UV energy received on any surface in the same position with regard to the sun calculated by equation:QUV,n=QUV,n-1+?tnUVG,nAr1000×Vt: ?tn=tn-tn-1 (2) Where tn is the experimental time for each sample (s), Vt is the total volume of wastewater at n water sample (L), Ar is illuminated collector surface area (m2), QUV,n is the accumulated energy (kJ/L), UVG,n is the average solar UV radiation during ?tn (W/m2).Results CharacterizationNano particles of Ti(1-x)O(2+x)Zrx were characterized by XRD (EQUINOX 1000-Inel), TEM (JEOL2011) and ICP (iCAP 6000) and BET (COULTER SA3100). These characterizations were carried out on the coatings when applicable, otherwise they were down on powder solids prepared in the same experimental conditions. The size of the prepared nanoparticles depended on the elemental concentrations in the precursor solutions. The average diameter of obtained crystallites ranged around 3.2 nm for x = 0 to x = 0,05. However the average diameter enhances to 4.2 nm when 0.3 x 0.7, results are reported elsewhere ADDIN EN.CITE <EndNote><Cite><Author>Cheng</Author><Year>2018</Year><RecNum>2</RecNum><DisplayText>(Cheng, 2018)</DisplayText><record><rec-number>2</rec-number><foreign-keys><key app="EN" db-id="0pe5espxbeevr3ep2xqvpspearr9f5aat9sv">2</key></foreign-keys><ref-type name="Thesis">32</ref-type><contributors><authors><author>Khley Cheng </author></authors><tertiary-authors><author>Andrei Kanaev Khay Chhor</author></tertiary-authors></contributors><titles><title>Development of mixed nano-photocatalysts based on metal oxide ZrxTi1-xO2

The XRD patterns of the solids with x > 0 show a shift of Bragg diffraction peaks indicating an increase of distances between the crystalline planes. The XRD patterns of Figure 2. show the anatase crystalline phases for both types of nanoparticles.Figure 2: XRD patterns of nanoparticulate ZrxTi(1-x)O2 solids with Zr content x = 0 and x = 5% heat treated during 4 hours at 410 °C.The thickness of the coatings was measured by ICP technique consisting of measuring the mass of TiO2, covering the surface of a known quantity of glass beads, dissolved in an acid solution. The total mass of the deposited TiO2 measured by ICP technique permitted to estimate the thickness of deposited TiO2 layer to =8 nm.The BET measurements indicated a significant increase of the specific surface area from 25 m2 when x = 0 to reach 70 m2 as a maximum at x = 0.05. The high specific surface area could be explained by the material porosity. A TEM image of Zr0.05Ti0.95O2 particles in Figure 3. evidences nanoporous morphology of the prepared solids.Figure 3: TEM image of nanoparticulate Zr0.05Ti0.95O2 solids.Photocatalytic activity on AMX abatement under solar irradiationThe solar irradiation power was measured for each experience. A typical UV solar irradiation pattern is presented on Figure 4. These measurements were used in order to calculate, by using equation (2) the solar energy deposited per litre of treated solution. During our experiments the UV irradiation increased from 100 uW/cm2 at 9,00 AM to 530 uW/cm2 at noon then decreased to 99 uW/cm2 at 5,00 PM. Figure 4: A typical UV solar irradiation pattern measured during the experimental days on the solar plant of University of Isfahan. Solutions of 10 mg AMX dissolved in 10 L distilled water were submitted to solar irradiation. The pH was adjusted at 7.5 and H2O2 (100 mg/L) was added to the solutions. Results depicted in Figure 5. show the degradation of AMX increases in all cases by exposing the solution to solar irradiation. The photolysis alone is responsible for 22% degradation of AMX when the irradiation energy reaches 40 kJ/L. The degradation of AMX reached 39% by using glass beads coated with Zr0.05Ti0.95O2 particles. In contrast glass beads coated with TiO2 show higher AMX degradation that reached 54% with an input energy of about 40 kJ/L. Comparative experiments with commercial TiO2 powder were carried out at the same conditions as those of the coated TiO2. In each experience one gram of TiO2 was added to 10 L of AMX solution. AMX degradation reached 65% at about 40 kJ/L. However the quantity of commercial TiO2 used to obtain this higher AMX degradation is much higher than the quantity of TiO2 coated on glass beads which has the advantage to be reused in next experiences.Figure 5: AMX abatement in 10L batch as a function of exposure to solar energy by using Zr0.05Ti0.95O2 and TiO2 coated on glass beads compared with commercial TiO2 and photolysisConclusionsTiO2 photocatalysis is a promising technology due to its capability of using natural solar UV energy which can reduced the cost of associated with UV radiation production. The reactor used in this study has a compound parabolic collector that shows the best performance. In order to access the influence of solar irradiance, photocatalytic experiments were carried out for three types of catalyst. The ZrXTi1–XO2 photocatalysts (X = 0, X = 0.05) were prepared and the photocatalytic performance was studied on Amoxicillin elimination in a solar photoreactor. Degradation percentage, after 240 min at the solar plant for commercial TiO2, TiO2 and Zr0.05Ti0.95O2, were achieved 69, 48, 38, respectively in pH = 7.5. Results showed that only nearly 40 kJ/L of accumulated UV energy was necessary for these efficiencies. The Zr doping of TiO2 shows lowering of the photocatalytic activity in our experimental conditions.Acknowledgments This work has been supported by the Centre for International Scientific Studies & Collaboration (CISSC) of I.R.Iran.Reference Alalm, M.
