Abstract

Objective: To study the adsorption of 5-Amino-2-chlorotoluene-4-sulfonic (CLT) and chlorhydric (HC1) acids from wastewater by weakly basic resin.

Methods: The kinetics and isotherm were studied. Thermodynamic parameters for the adsorption of acids were calculated and discussed.

Results: The adsorption of CLT and HC1 acids followed Langmuir isotherm and the first-order kinetics model.

Conclusion: 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.
