【摘要】 实验发现,Sb(V)和As(V)在铜电解精炼过程可形成砷锑酸,砷锑酸继续与电解液中的As(III)、Sb(III)、Bi(III)作用能形成砷锑酸盐,砷锑酸盐中的As(III)、Sb(III)、Bi(III)在含Cl-的强酸性溶液中可分离。利用砷锑酸盐的这一特性,合成了对铜电解液中As、Sb、Bi具有良好选择性且能重复使用的吸附剂。更多还原

【Abstract】 It has been discovered in experiments that Sb(V) and As(V) can lead to the formation of arsenical antimonic acid during the refinery process of copper electrolysis. The arsencial animonic acid will continue to form salts of As(III), Sb(III) and Bi(III) contained in the electrolytic solutions. The As(III), Sb(III) and Bi(III) in the salts will separate in the strong acidic solution containing [(Cl)(-)(1)]. Using this property of the arsenical antimonates, a new absorbent has been compounded, which shows a good selectivity to As, Sb and Bi in the copper electrolytic solutions and which can be recycled [(for use.)0( )][(更多还原
