Key Points

The sorption was conducted at 293, 303, and 3130.1 K for 48 h from 10-5-10-4 M solutions in the presence of 10-3 M NaCl. From the kinetic experiments it was found that this time was sufficient to attain the adsorption equilibrium. The first stage of the sorption (up to 160 min) can be well described by a first-order kinetic equation by its ... ................
