测定可逆反应动力学参数的一种新方法

A New Method for Determination of the Kinetic Parameter of Reversible Reaction

提出了测定一级可逆反应速率常数的新方法,用以测定稀土的偶氮胂Ⅲ络合物与CyDTA交换反应的速率常数,并详细讨论了测定速率常数时动力学数据的选取原则。

A new method for determination of the reaction rate constant in the reversible pseudo first-order reaction was proposed. By this method, the rate constant of ligand exchange reaction between arsenzao Ⅲ coordinating with rare earth and CyDTA was determined. The principle of selecting kinetic data, which were used to calculate the reaction rate constant, was discussed in detail. The kinetic parameters have been applied to the differential kinetic analysis of binary mixture of rare earth with a satisfactory result.
