采用蒋洪圻和徐光宪的处理方法,用极谱法研究了亚铊离子和乙酸根的络合,得到TlAc和Tl(Ac)2-的逐级稳定常数分别为:K1=0.0661,K2=0.178(25℃,μ=3.00,用NaClO4维持).

The half-wave potential of the thallous ion was determined at 250C in sodium per-chlorate-sodium acetate mixtures over the range of 0-2.0 M sodium acetate at an ionic strength of 3.00.From the data, the existence of Tl(Ac)2- was revealed, in addition to the species TIAc and Tl+ as found by previous investigators[1,2].The successive stability conslants were found to be: K1=0.0661۪.01, K2=0.178۪.03，where Ki=[MLi]/[M][L]i.
