在水溶液的络合平衡研究中,pH电位法得到广泛应用,但有一定局限性。G·Shwarzenbach提出的pH-pM同时测定法原则上可以处理多级酸式络合常数,但实验受到仪器的限制。借助徐光宪的络合物吸附平衡理论可以将Y_0(Frouaeus函数)与_L(生成函数)相联系,从而可能将上述两种方法沟通起来。但文献[2]所介绍的方法只适于求各级正常络合物常数。 In the complex equilibrium study of aqueous solution, pH potential method has been widely used, but there are some limitations. The pH-pM simultaneous assay proposed by G. Shwarzenbach can in principle handle multi-stage acidic complexation constants, but experiments are limited by instrumentation. With Xu Guangxian’s theory of complex adsorption equilibrium, Y_0 (Frouaeus function) can be related to _L (generation function), so that the above two methods may be communicated. However, the method presented in [2] is only suitable for finding normal complex constants at all levels.
