摘　　要：本文对金属双硫腙盐 Hg(HDz)_2和 Zn(HDz)_2在几种高分子介质中的可见光谱和异构复原反应动力学行为进行了测定分析。结果发现:高分子介质的改变并不影响金属双硫腙盐可见吸收光谱中最大吸收波长的位置,在高分子介质中与在有机溶剂中不同,在高分子介质中金属双硫腙盐的异构复原反应基本上表现为两个阶段;先快后慢(Hg(HDz)_2在火棉胶中例外),而不像在有机溶剂中那样简单地遵从一级反应动力学规律.The absorption spectrum and the kinetics of the return reaction of metal dithizonates Hg(HDz)_2 and Zn(HD_z)_2 in polymer matrix have been studied in this paper.The results are:the maximium wavelength of metal dithizonates do not change with changing polymer matrix.The kinetics of the return reaction of metal dithizonates in polymer matrix differs with that in organic solvents.The kinetics of the return reaction of metal dithizonates in polymer matrix include two steps,first fast and then slow and it does not follow first-order reaction kinetics simply.
