Frensdoff~[1] 曾用离子选择电极电位法测定冠醚与金属离子配合物的稳定常数.该文虽提到采用非线性最小二乘法处理实验结果,但未给出具体计算步骤和计算程序.本文用电位法测定了新合成的四种苯并-15-冠-5含偶氮基的衍生物与钠、钾离子配合物在甲醇中的稳定常数,并用自编的计算程序处理实验结果.
Frensdoff ~ [1] has used ion-selective electrode potential method to determine the stability constants of the complex of crown ether with metal ions. Although the article mentioned the use of nonlinear least square method to deal with the experimental results, but did not give specific calculation steps and calculation procedures. Potentiometric method was used to determine the stability constants of four newly synthesized benzo-15-crown-5 azo-containing derivatives and sodium and potassium ion complexes in methanol. The experimental results .
