| 摘 要： | 对配位体亲核竞争取代反应分光光度法的光谱特征、波长选择、配合物竞争能力和金属离子水解问题进行了较为详细的讨论。该方法通过已知稳定常数的配合物作为指示配合物，由体系光密度和ＰＨ值的变化，可直线外推求解配合物的逐级稳定常数和摩尔消光系数。

| Abstract: | Condition selection of spcetrophotometric method for ligand competitionreplacement reaction, concerning about spectroscopy characteristic, choice of wavelength and competition ability of metal complexes as well as hydrolysis of metal ionhad been discussed in detail. The method can be applied for the determination of successivestability constants and molar extinction coefflcients of metal complex by straight lineextrapolation . |
