中文摘要: 采用TBP和N1923协同萃取铜电解液中的砷、锑、铋，考察TBP和N1923的浓度、电解液酸度、相比、时间、反萃取相比等因素对萃取过程的影响。结果表明，当有机相组成为60%TBP 25%N1923 5%异辛醇 10%磺化煤油，萃取相比O/A=3时，砷、锑、铋的单级萃取率分别为58.01%，53.49%和68.97%。反萃相比O/A=2时，用水反萃砷的单级反萃率为53.61%。在反萃液组成为反萃剂 50 g/L、硫酸1 mol/L，反萃相比O/A=2时，锑、铋的单级反萃率分别为58.63%和79.46%。
Abstract:Synergistic extracting of As, Sb and Bi from Cu electrolyte with TBP and N1923 was carried out. The effects of various factors such as concentrations of TBP and N1923, electrolyte acidity, ratio of organic to aqueous phase(O/A), reaction time, and stripping phase ratio were investigated. The results show that the single-stage extraction rate of As, Sb and Bi are 58.01%，53.49% and 68.97% respectively when the organic phase composition is 60% TBP 25% N1923 5% isooctanol 10% sulfonated kerosene, O/A is 3, reaction time is 4 minutes. The single-stage water stripping rate of As is 53.61% with O/A=2. The single-stage stripping rate of Sb and Bi are 58.63% and 79.46% respectively with 50 g/L stripping agent, 1 mol/L H2SO4 and O/A=2.
