Abstract

Chromium is one of the heavy metals that is found in industrial effluents and is very toxic for human and environment. In this work the removal of hexavalent chromium by using of ADSORPTION onto strongly basic anion was investigated. Various parameters such as pH, initial hexavalent chromium concentration, contact time and RESIN dosage were studied. Experimental data were expressed by Langmiur and Freundlich isotherm Pseudo-first order, Pseudo-second order and modified Pseudo-first order KINETIC MODELs. The results showed chromium removal was increased by increase of contact time and RESIN dosage, while decreased by increase of pH and initial hexavalent chromium concentration. At contact time equal 120 min, RESIN dosage 0.2 g/100 ml and initial hexavalent chromium concentration of 30 mg/l, by increasing pH from 3 to 11, removal efficiency was decreased from 93.56% to 69.12%. In addition, by increasing contact time from 5 min to 120 min, removal efficiency was increased from 39.51% to 94.41%. The results also showed hexavalent chromium sorption follows Langmiur ISOTHERM MODEL. Pseudo second order models best describe chromium removal by using of ADSORPTION onto strongly basic anion RESIN. The results revealed that removal of hexavalent chromium from aqueous solution by using of ADSORPTION onto stringly basic onion RESINs can be done quick and effective.
