Abstract By the reaction Fe3+,Co2+,Ni2+,Cd2+ and Hg2+ with fiber containing amidoxime groups modified polyacrylonitrile fiber(AOCF), a series of coordinate complexes-AOCF-Fe(Ⅲ),AOCF-Co(Ⅱ),AOCF-Ni(Ⅱ),AOCF-Cd(Ⅱ) and AOCF-Hg(Ⅱ) were prepared in acid medium. The fibers containing amidoxime groups with and without metal ions were taken for FTIR in the range of 4 000-400 cm-1. Their major bonds were assigned and compared. The results showed that in all complexes some bands (νC—N,νCN and νN—O) were strengthened and a certain shift to higher wave number took place in the FTIR spectra with 4-21 cm-1 shifts observed. The amidoxime groups and metal ions were bonding with coordinated bond.
