Removal of Orange-G and Alizarin Red S from Aqueous Solution by CuCl2 Doped Polyaniline Composite Assisted by UV light

摘要

This work describes the adsorption of Orange-G and Alizarin Red S, from aqueous solutions onto 8 % PANI-CuCl2 adsorbent. Adsorption studies were performed by UV light irradiated batch experiments as a function of process parameters such as contact time, initial dye concentration, dosage of adsorbent and initial pH. Temperature was varied to investigate its effect on the adsorption capacity. Equilibrium adsorption isotherms were measured and the experimental data were analyzed by using Langumuir equation. Pseudo-second-order kinetic model was found to correlate with the experimental data well. The experimental data obtained in the present study indicates that CuCl2 doped with polyaniline can be attractive options for removal of dye from waste water.
