| 摘 要： | 在氮气氛围中利用低能电子束预辐照接枝法，在低密度聚乙烯（LDPE）上接枝丙烯腈（AN）进而通过酸性水解、霍夫曼降解，制备一种胺型螯合树脂（LDPE-g-VAm），并考察这种螯合吸附材料对铜离子的吸附性能；研究了铜离子的质量浓度、吸附时间、pH值及循环次数对铜离子螯合吸附能力的影响规律；同时对吸附材料进行全反射红外（FT-IR）的表征。

| Abstract: | A study was made on the preparation of a chelating material with amidocyanogen by three steps ,including pre-irradiation grafting of acrylonitrile（AN） onto low-density polyethylene（LDPE） membrane,hydrolysis in acid conditions and Hofman degradation. The equilibrium sorption for Cu2+ was studied and the effect of mass concentration of Cu2+,time and pH on sorption capacity were also discussed . The result showed that this kind of resin had strong absorbing ability to Cu2+, and the structure of the material was characterized by FTIR. |
