Adsorption study of Zn^2^+ cation and SCN^- anion from complex solution on alumina

Abstract

The adsorption characteristics of Zn2+ cation and SCN- anion from the complex solution on g-alumina samples pretreated with nitric acid of different concns. were investigated. The effects of pH, concentration, time, temperature, ionic strength and chelating agents are investigated. The experimental results were interpreted by using a predominant ion-exchange mechanism. Both the surface hydrolytic action and the complexation may occur at the oxide/water interface.

Key words: SPECTROPHOTOMETRY, ZINC, ALUMINIUM OXIDE, ADSORPTION, ION EXCHANGING, THIOCYANATO COMPLEX, IONIC STRENGTH, SOLUTION CHEMISTRY, INTERFACE CHEMISTRY, ADSORPTIVE COMPLEX WAVE
