离子交换法测定溶液中络合物稳定常数是近十几年来才开始的,溶解度法是测定络合物稳定常数的经典方法之一,均有专论。溶液中混合型络合物稳定常数的测定也是近十几年才开始的,国内有过评介。但用阳离子交换法和溶解度法测定溶液中混合型络合物的稳定常数还未见报导。最近徐光宪等用萃取法以作图外推法测得混合型络合物稳定常数。本文尝试推导了用阳离子交换法和溶解度测定单核双配位体络合物稳定常数的有关公式。
Ion exchange method for the determination of complex stability constant in solution in the last decade or so, the solubility method is to determine the stability of the complex complex one of the classical methods, are monographs. The determination of the stability constant of the mixed complex in solution also started in recent ten years. However, the cation exchange method and the solubility method for determining the stability constant of the mixed complex in solution have not been reported yet. Recently, Xu Guangxian other extraction method to determine the stability of the mixed complex measured by extrapolation. In this paper, we try to deduce the formula for determining the stability constant of mononuclear bidentates complexes by cation exchange and solubility.
