| Abstract: | This work is dedicated to adsorption study of Ni(II) ions by synthetic adsorbent based on ma-leic anhydride styrene copolymer and 4-Amino-N-2-thiazolylbenzenesulfonamide modified with thi-ourea. During work different parameters affecting adsorption process were investigated such as influence of pH, contact time, ionic strength and initial metal ion concentration. It was found that maximum adsorption capacity is observed at pH=3 and is equal to 18 mg/g. In order to describe adsorption process different adsorption isotherm models were studied and the results were found to be consistent with the Langmuir model. Dubinin-Raduskhevic model was investigated to show that physical adsorption takes place in the system adsorbent-adsorbate. The present work also includes desorption studies and 0.5 mol/l solution of HNO3 has shown the highest desorption capacity over Ni(II) ions. |
