Towards the isolation and estimation of elemental carbon ...

tures like graphite, carbon nanospheres, multiple aromatic layers, and chars with low H/C and O/C ratios [9–11]. Some huge three-dimensional organic polymers may also be regarded as EC [12, 13]. OC is a combination of organic compounds with smaller masses, e.g., non-volatile hydrocar-bons, organic acids, and anhydrous sugars. OC originates ................
