Adsorption Modelling

Abstract

In this study, adsorption was explored to remove toxic metals from wastewaters. The main focus of the research work lies on adsorption process, which is described theoretically and studied experimentally. Theoretical part involves studying of the adsorption concepts, adsorbents and adsorption process modelling. Experimental part of the work was aimed to create a condition which will allow examining the adsorption process by using adsorbents to remove toxic metal from aqueous solution. The experiment was divided on analysing optimum concentration and optimum time periods to remove Zn(II) and Cu(II) from aqueous solution by using studied adsorbents. Secondly, the determination of pH values when adsorbents have the highest adsorption capacity was required to study. The gathered data were applied to model adsorption process via kinetic and isotherm adsorption models. The target of research was reached: all results of experimental part were satisfactory to be described and concluded by theory.
