最近提出一种新的处理数据方法,可由溶液的物理化学性质的测定(如光密度、热效应等)直接求络合物的各级稳定常数,而不需要通过平均络合数或络合度φ的计算等经典方法。上述作者将它列为测定稳定常数的第二类方法,有别于第一类方法如极谱法、电势法、溶解度法、分配法等。但是,由于第二类方法在计算上比较复杂,只推导出形成两个络合物MA,MA_2时计算β_1β_2的式,对于三种逐级络 Recently, a new data processing method was proposed. The stability constants at various levels of the complex can be obtained directly from the determination of the physicochemical properties (such as optical density and thermal effect) of the solution without the need of calculating the average complexation number or the degree of coordination φ The classic method of calculation. The authors listed it as a second method of determining the stability constant, unlike the first method such as polarography, potentiometry, solubility, distribution and so on. However, since the second kind of method is computationally complex, only the formula for calculating β_1β_2 when two complexes MA and MA_2 are formed is deduced. For three kinds of stepwise networks
