KINETICS OF ADSORPTION OF ACID RED 1 ONTO CHITOSAN AND CROSS-LINKED CHITOSAN FROM AQUEOUS SOLUTION

Chitosan(CS) and crosslinked-Chitosan (CCS) (Chitosan+Glutaraldehite) were utilized as adsorbents to remove acid red1(AR1) from aqueous solution by adsorption. Batch experiments were conducted to study initial concentration of adsorbate and temperature on dye adsorption. The kinetic data obtained from different batch experiments were analyzed using pseudo first-order and pseudo second-order and Weber-Morris equations, and the rate constants of first-order adsorption (kpf), the rate constants of second-order adsorption (kps) and intraparticle diffusion rate constants (kid) at these concentrations and temperatures were calculated, respectively.
