Mechanism and kinetics of the sorption of platinum, palladium, and gold on activated carbon from UV-illuminated chloride solutions

Abstract

The mechanism and kinetics of the sorption preconcentration of gold, platinum, and palladium on activated carbon from solutions exposed to ultraviolet (UV) radiation were studied. The thermodynamic parameters of sorption (sorption capacity and type of adsorption isotherm) were determined; the effect of pH was considered. An explanation of the mechanism of the effect of UV illumination on sorption preconcentration was proposed. It was demonstrated that UV illumination does not change thermodynamic parameters of sorption but significantly affects the kinetics of sorption preconcentration.
