用三氯化锑的盐酸溶液电解制备高纯锑,国外曾有人报导过。我们也曾研究过这个方法,同时,注意到三氯化锑在不同浓度盐酸中的吸收光谱尚无系统测定资料,尤其是,其中的各种络离子的稳定常数等未见报导。H.M.Neuman等研究了锑(Ⅴ)在盐酸溶液中的紫外吸收光谱及其中络离子的品种与含量。为了进一步了解锑(Ⅲ)在盐酸溶液中的络离子的情况,本研究把试验分为两个部分:
Antimony trichloride hydrochloric acid solution of electrolytic preparation of high-purity antimony, it has been reported abroad. We have also studied this method. At the same time, we noted that there is no systematic data on the absorption spectra of antimony trichloride in different concentrations of hydrochloric acid. In particular, the stability constants of various complex ions therein have not been reported. H.M. Neuman et al. Studied the UV absorption spectrum of antimony (V) in hydrochloric acid solution and the species and content of its counter ions. In order to further understand the complex ions of antimony (Ⅲ) in hydrochloric acid solution, the study divided the experiment into two parts:
