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 4000-400 cm(-1). Their major bonds were assigned and compared. The results showed that in all complexes some bands (vC-N, vC=N and vN-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.
通过Fe3+、Co2+、Ni2+、Cd2+和Hg2+与含偕胺肟基的改性聚丙烯腈纤维（AOCF）反应，在酸性介质中制备了一系列配位络合物——AOCF-Fe(III)、AOCF-Co(II)、AOCF-Ni(II)、AOCF-Cd(II)和AOCF-Hg(II)。对含偕胺肟基且有和没有金属离子的纤维进行了4000 - 400 cm(-1)范围内的傅里叶变换红外光谱（FTIR）分析。对其主要化学键进行了归属和比较。结果表明，在所有络合物中，一些谱带（vC-N、vC=N和vN-O）得到增强，并且在FTIR光谱中出现了向高波数的一定位移，位移范围为4 - 21 cm(-1)。偕胺肟基与金属离子通过配位键结合。
