摘要
以KCl、KBr、KI、KNO3为支持电解质,在pH值为1.5~3.0范围内,设计两种模型,研究了Cu(Ⅱ)与水溶性中位-四(4-N-氰乙基吡啶基)卟啉(TγNPNPγP)的反应动力学,利用计算机线性回归拟合,得出了其表现速率常数的一般表达式。研究表明,Cu(Ⅱ)与TγNPNPγP嵌入反应速率顺序为KCl介质〉KBr介质〉KI介质〉KNO3介质,这与Cu(Ⅱ)和Cl^-、Br^-、I^-、NO3^-形成配合物时的稳定性是一致的,表明平衡阴离子也参与了配位。
The kinetics of the insetting reaction of Cu( Ⅱ ) and γ-tetra- (4-cyanoethylpyridyl)- porphyrin were studied in KCl, KBr,KI, KNO3 solutions at pH value 1.5-3.0 (35℃). The rate constant equation was given by linear regression analysis. Coinciding with stability of the complexes, the rate of insetting reaction decreased in the following order:KCl〉KBr〉KI〉KNO3. The results indicated that the anion ions were involved in the coordination.
