Abstract

The paper reports the removal of Chrysoidine R, a toxic mono-azo dye from its aqueous solution by employing metal- and halide-free variant of ordered mesoporous carbon as adsorbent in batch experiments. The influence of various parameters such as hydronium ion concentration, adsorbent dosage, initial dye concentration, exposure time on dye uptake was studied. The process could be described by Langmuir, Freundlich and Dubinin-Radushkevitch isotherm models. Evaluation of thermodynamic variables proved that the adsorption was spontaneous, feasible and endothermic. The kinetics involved in the process was worked out using pseudo-first-order and pseudo-second-order kinetic models. The latter was found appropriate for the analysis of the experimental data. The mechanism governing the overall adsorption was elucidated with the aid of various mathematical models. The adsorption was found to proceed via film diffusion with chemisorption being the rate-determining step. The complete removal of dye with fast removal rate makes the material propitious in the field of water treatment.
