In order to prepare a new type adsorbent with an affinity ligand for treatment of V(V) and Pd(Џ), pp fibers modified with amino such as ethylene diamine (EDA), imino diacetic acid (IDA) and phenylhydrazine (PH) were prepared by radiation-induced grafting of acrylonitrile (AN) onto pp fibers and subsequent amination of poly-AN graft chains. Results show that the longer amination time and higher temperature gain the higher conversion yield. FTIR test indicate that amine group was introduced into PP-g-AN fiber through amide linkage between grafted AN and EDA, PH or IDA. |
