Removal of 5-amino-2-chlorotoluene-4-sulfonic and chlorhydric acids from wastewater by weakly basic resin: equilibrium and kinetics.
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.


CONCLUSIONS
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.
