Investigation of adsorption parameters such as effect of initial acid concentration, effect of amount of adsorbent, effect of temperature,;, effect of contact time, fitting data to isotherms, and kinetic models for propionic acid and tartaric acid by using Amberlite IRA-67 adsorbent was studied. The maximum adsorption efficiencies were found to be 97.18% and 84.46% for tartaric acid and propionic acid, respectively. The best fitted isotherm was determined to be Langmuir for tartaric acid. The Langmuir isotherm was better fitted than the Frundlich isotherm for both acids. Elovich model equation was applied for data of each acids. The kinetics of the adsorption for both acids was determined as pseudo-second-order model.
