Experimental and Theoretical Study of The Adsorption Behavior and Electrical properties For Some Substituted Benzoic Acid And The Complexation Surface Model From Electrical Conductivity

Abstract

The study including the isotherm adsorption of some substituted of benzoic acid from solutions by using activated charcoal prepared by chemical treatment. This study gives a clear effect of the substituted group on the adsorption as well as obtained a higher adsorption at diluated concentration.The relation between the efficiency of adsorption and distribution coefficient was calculated and study the changing in electrical properties after adsorption to arrive to the models of how the acid molecules binding with surface of charcoal. This results refrecement with theoretical study for the factors affecting adsorption process which enforcement with experimental results.
