Abstract

This paper contains researches regarding the influence of temperature on the kinetic mechanism of nickel fixation by using cationic clays. The separation of nickel from dilute aqueous systems is studied for environmental protection and nickel recovery. In this paper was studied the fixation of nickel from dilute aqueous solutions by ion exc hange with crude clays in direct relation with temperature. The results, showing the direct dependence for ion exchange process with working conditions.
