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