摘要
采用离子选择性电极电位法,以非线性最小二乘法处理实验结果,分别对四种有色冠醚与钠,钾离子配合物在甲醇-水溶液中的稳定常数进行了测定,结果与文献值比较,变化趋势一致。
The stability constants for the coordinatcs of coloured crowns with sodium and potassium ions in methanol/water mixed solvents have been determined with ion-selective electrodes. A non-lincar method of least squares for treatment of data is described. The results show that the trend of change is consistent with that in literature.
