Adsorption of cobalt (ii)‎ ion from aqueous solution on selected Iraqi clay surfaces

Abstract EN

This work is concerned with one of application of adsorption behavior from aqueous solution.

It deals with the study of adsorption of Cobalt (II) ion on the surfaces of Attapulgite, bentonite, and kaolin, which are provided locally in Iraq.

The purpose of this study is searching for surfaces that are highly applicable for Cobalt (II) ion adsorption to treat the pollution of aqueous solution in nature by this heavy metal ion.

This study also involves the feasibility of using (NH4SCN) (Ammonium thiocyanate) for Visb-spectrophotometric determination of Cobalt (II) ion and to determine the relation between the adsorption quantity of Cobalt (II) ion and equilibrium concentrations (adsorption isotherm) in different conditions of temperature, ionic strength, pH, practical size, and adsorbent weight.
