Studies On Adsorptive Removal Of An Antibiotic Drug Using Ion Exchange Resin.

Authors : Kais H. . Yeddou-mezenner N. .

Abstract

This study explores the adsorption feasibility of an antibiotic (rifampicin) onto the amberlite IRA-420 resin. The effect of rifampicin concentration (10–30 mg/L), contact time, adsorbent dose (1-3 g/L), solution pH (4-10.5) on the pharmaceutical adsorption on amberlite IRA-420 is investigated. The experimental results indicate that the optimal pH for the rifampicin elimination is the free pH for an adsorbent dose of 1 g/L. The Langmuir model describes well the isotherm data with a high correlation coefficient (R2> 0.944) and a maximum monolayer adsorption capacity of 77.04 mg/g at 295 K. The comparison of the pseudo-second-order and Temkin kinetic models; shows that the experimental data are well fitted by the pseudo second-order kinetic model.
