Synthesis and Adsorption Property of Polyethylene-N, N-dithio-carboxyl Diethylenetriamine
Abstract:Polyethylene N,N dithio carboxyl diethylenetriamine was synthesized by reaction of 1,2 dichloroethane with the intermediate product (N,N dithio carboxyl diethylenetriamine) obtained from the reaction of carbon disulfide with diethylenetriamine. The intermediate product and polymer were characterized by means of infrared spectroscopy. The polymer's adsorption property towards a series of heavy metal ions was examined. The results showed that the polymer could adsorb some heavy metal ions in certain amount and the adsorption capacity for Ag+ and Cu2+ was higher than that for other metal ions.
Keywords:dithio-carboxyl polymer  heavy metal ion  adsorption property
