摘要
根据DeFord的基本理论,先后对Pb2+、Tl+同新合成的冠醚2,3苯并11甲基18冠6,2,3苯并8,11,15三甲基18冠6所形成的配合物进行极谱测定,并采用线性规划,非负最小二乘法对所得实验数据进行计算机优化处理,测得金属离子同新合成冠醚所形成配合物的稳定常数。本方法简便快速。
The stability constants of metal cation and crown ether compound have been measured polarographically according to the basic formula of DeFord. The experimental data are processed using computer with the method of linear programming and nonnegative least squares. The stability constants of metal ion Tl +、 Pb 2+ and crown ether 2,3 benzo 11 methyl 18 crown 6,2,3 benzo 8,11,15 trimetry 18 crown 6 are determined.
