Preliminary performance study of synthetic Alumina nanoparticles for retention of cobalt and cesium cations.

In the present study, a facile nano-sized gamma alumina was synthesized and then examined for immobilization of cobalt and cesium ions individually from aqueous solutions. The comprehensive analysis of functional groups, phase composition, surface morphology and sorption characteristics of the synthesized nano-sized ϒ alumina was executed. It was deduced that acquired material was low-crystalline with a high elimination efficacy towards the concerned cations under slightly alkali and acidic conditions. Time-transient elimination scrutiny was executed and cobalt elimination rate was found relatively faster than cesium cations. Equilibrium sorption examinations confirmed that the sorption is proceeding via two diverse sites on the scavenger surface. Cobalt and cesium elimination is a spontaneous endothermic reaction of increased chaos. The attained results proved the high proficiency of the synthesized scavenger in the cations immobilization.
