本文研究了“配体竞争一等色点光度法”测定高稳定性配合物的稳定常数,利用该法研究铜(Ⅱ)与PRA的配位反应,测得该反应生成1:1型配合物1gK_(ML)=16.44,1:2型配合物1gK_(m12)=25.93。
In this paper, the stability constants of high stability complexes were determined by the “first-order ligand colorimetric method”. The coordination reaction between copper (Ⅱ) and PRA was studied by this method. The results showed that this complex formed 1: 1 1gK_ (ML) = 16.44, 1: 2 complex 1gK_ (m12) = 25.93.
