本文用极谱法证明亚铊离子与硫氰酸根在水溶液中生成配位数自1至6的六种络合物,它们的稳定常数依次为K1=4.38±0.04,K2=7.59±0.18,K3=5.04±0.19,K4=5.37±0.42,K5=3.33±0.52,K6=2.88±0.93。

The half wave potential of the thallous ion was determined at 25° in sodium perchlorate-sodium thiocyanate mixtures over the range of 0.05-2.0 M thiocyanate concentration at an ionic strength of 3.00. A modified type of H-cell was proposed in order to prevent the diffusion of chloride ions from the calomel electrode to the solution being investigated.
