在1983年发表的一篇著作中我们曾指出:铋、锑的硫脲络合物用醋酸乙酯萃取后,铋、锑有可能在不外加极化电压的情况下浓集于悬汞电极上。从非水溶剂中浓集的方法扩大了络
In an article published in 1983, we pointed out that the bismuth and antimony may be concentrated on the hanging mercury electrode without the application of polarized voltage after the thiourea complex of bismuth and antimony is extracted with ethyl acetate . Enrichment from non-aqueous solvents expands the network
