摘要
The removal of acetic acid and glycolic acid from aqueous Solution by the weakly basic adsorbent Amberlite IRA-67 has been Studied at three different temperatures. Amberlite IRA-67 removed both acids very well from aqueous Solution. The maximum adsorption efficiency has been found to be 86.29% and 61.36% for glycolic acid and acetic acid, respectively. Langmuir and Freundlich adsorption isotherms have been applied to the experimental data. The Langmuir isotherm fitted the experimental data better than the Freundlich isotherm for both acids. Thermodynamic parameters Delta G, Delta H, and Delta S were calculated.
