摘要

用紫外-可见光谱法研究了对-四羟基苯基卟啉(简称P0)在不同胶束体系中与Zn(Ⅱ)

Cu(Ⅱ)的反应动力学

并对不同胶束微环境对P0与过渡金属离子络合的动力学影响进行了初步探讨.实验结果表明:当两种金属离子浓度大大过量时

P0与Cu(Ⅱ)

Zn(Ⅱ)的反应为准一级反应

CuP0的生成速率远远大于ZnP0的生成速率

其原因与过渡金属离子的半径有关;在胶束体系中

增溶位置决定了P0与金属离子络合反应速率常数的大小

P0在不同类型的表面活性剂胶束中与金属离子络合的反应速率常数为KSDSKCTABKTX-100.

Abstract

The kinetics of 5

20-tetra(4-hydroxyphenyl)-porphyrin(P0) with Zn(Ⅱ)

Cu(Ⅱ) in micellar system have been investigated by UV-Vis spectra

and the dynamics effects of complexes at different micelles have been discussed preliminary.The results show that

the reaction of P0 with Cu(Ⅱ) and Zn(Ⅱ) is pseudo first-order when the two concentration of metal ion are in large excess

Metallation rate of P0 is effected by metal ions

the reaction rate constants in SDS and CTAB are KCu(Ⅱ)KZn(Ⅱ).The reaction rate of P0 cooprated with Zn(Ⅱ)

Cu(Ⅱ) in micellar solution can be controlled by the solubilization site of P0 in micellar solution

the reaction rate constants of P0 in three micelles decreased in the sequence of KSDSKCTABKTX-100.
