本文用极谱法证明碘离子和镉离子在水溶液中生成配值数自1到6的六种络合物,其各级稳定常数,在以高氯酸钠为维持溶液离子强度的惰性支持电解质时,在25℃时,K1=40.74±0.4,K2=(3.72±0.12)×102,K3=(2.95±0.02)×104,K4=(2.37±0.07)×105,K5=(1.04±0.10)×105,K6=(3.70±0.10)×104.同时也测定了在18℃和30℃时的各级稳定常数.

The half wave potentials of cadmium ion were determined at 25℃ in sodium per-chlorate-sodium iodide mixtures over the range of 0.01-2.50M iodide ion concentration at an tonic strength of 3.00.The errors in the difference between the half wave potentials of the simple and the complex ions were estimated to be less than ±0.2 mv.
