A Study on the Effect of Appearance of Chelate Resin Matrix and Its Chemical Composition on the Adsorption Ability of Heavy Metal Ions(II) -Graft Copolymerization of 2-Methyl-2-oxazoline onto Chloromethylpolystyrene in the Presence of Catalyst and Its Adsorptivity to Heavy Metal Ions-

Chelate Resin Matrix의 외관과 그 화학적 조성이 중금속 흡착능에 미치는 영향에 관한 연구(II) -촉매하에서 2-Methyl-2-oxazoline의 Chloromethylpolystyrene에 대한 그라프트 공중합과 중금속 흡착능에 관하여-

The effect of catalyst (KBr KI) on the graft copolymerization of 2-methyl-2-oxazoline onto crosslinked chloromethylpolystyrene (PCMS) was investigated in terms of halogen exchange reaction. Relationship between crosslinking ratio and the degree of polymerization of graft polymer was studied through autocrosslinking reactions of PCMS resin matrix itself. Polyethyleneimine type chelate resin, obtained from graft copolymer by hydrolysis, proved to be effective for the adsorption of heavy metal ions such as Cr+2 , Hg+2, Pb+2 in the aqueous solutions. Finally the influence of pH and concentration of the metal ions on the retention was determined.
