(1)得到在电极反应可逆的条件下,极谱半波电势与络离子的各级稳定常数之间的一般的关系式——(22)及(23)两式;(2)讨论了一般关系式与前人已得的若干特殊公式之间的关系:(3)得到可以作为计算每一络离子的扩散系数的基础的(30)式。

A general expression has been obtained' for the evaluation of the successive stability constants of complex ions both in the higher and lower valence states from polarographic data. In four special cases, the general expression can be reduced to the results obtained by Lingane (1941), de Ford and Hume(1951),and Jachemirskii (1953). An expression is also provided for the evolution of the diffusion constants of individual complex ions from the measured diffusion current constants.
