Comparing the effect of contact time at Nickel(II) adsorption on poly(styrene-co divinyl benzene) beads before and After functionalization

poly (styrene-co-divinylbenzene) with high amounts of cross-linker (DVB) and diverse proportions of diluent agent (porogen) are synthesized according to the methodology of the suspension polymerization technique. Also it was functionalized by sulfuric acid. The applicability of poly(styrene-co-divinyl benzene) beads to separation and concentration of Ni(II) is discussed. In separation of Ni(II) from aqueous solution the effect of contact time for poly(styrene-co-divinyl benzene) beads before and after functionalization are discussed. To measure the ion concentrationin the solution used the UV–vis spectrophotometer. It was found that the optimal conditions for Ni(II) separation from aqueous solution for poly (styrene-co-divinylbenzene) is 180 minute while after functionalization is 5 minute. So that with functionalization, therefore separation of Nickelions by ion exchange, adsorption process as well as improved.
