Removal of 5-amino-2-chlorotoluene-4-sulfonic and chlorhydric acids from wastewater by weakly basic resin: equilibrium and kinetics / 生物医学与环境科学（英文）

ABSTRACT

<p><b>OBJECTIVE</b>To study the adsorption of 5-Amino-2-chlorotoluene-4-sulfonic (CLT) and chlorhydric (HC1) acids from wastewater by weakly basic resin.</p><p><b>METHODS</b>The kinetics and isotherm were studied. Thermodynamic parameters for the adsorption of acids were calculated and discussed.</p><p><b>RESULTS</b>The adsorption of CLT and HC1 acids followed Langmuir isotherm and the first-order kinetics model.</p><p><b>CONCLUSION</b>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.</p>
