Type: article
Abstract: This work is dedicated to adsorption study of Ni (II) ions by synthetic adsorbent based on maleic anhydride styrene copolymer and 1,4-bis[2-(prop-1-enil) fenoksi]butan modified with N, N'-diisopropyl thiourea.During work different parameters affecting adsorption process were investigated: 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 19.5 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.
