ABSTRACT
To study the adsorption of 5-Amino-2-chlorotoluene-4-sulfonic (CLT) and chlorhydric (HC1) acids from wastewater by weakly basic resin. The kinetics and isotherm were studied. Thermodynamic parameters for the adsorption of acids were calculated and discussed. The adsorption of CLT and HC1 acids followed Langmuir isotherm and the first-order kinetics model. The adsorptive affinity of the two acids on D301R is in the order of CLT acid > HCl acid. CLT and HCl acids can be separated.
