方法用电位滴定法测定酸度常数。质子化函数ñH定义为束缚于L的H+离子的平均数目，由式2给出。AGf、AHf和ASf是反应la、lb和lc在摩尔浓度尺度上的热力学函数变化，描述了H、L′+的电离。由于二乙烯三胺是一种重要的络合剂，因此测定AGf值的频率很高；AHf和ASf值也是re-
Method Determination of the Acidity Constants by Potentionmetric Titration. The protonation function ñH, which is defined as the average number of H+ ions bounded to L, is given by eq 2.AGf, AHf, and ASf are the changes of the thermodynamic functions in the molarity scale of reactions la, lb, and lc, describing the ionization of H, L ‘+. As diethylenetriamine is an important complexing agent, AGf values have been determined quite often; AHf and ASf values are also re-
