摘要
采用重差分相液膜(GSPLM)分离技术,以P204为载体,H2SO4为反萃剂,对初始浓度为552mg/LCu2+水溶液提取4次后,其浓度降至101mg/L,反萃相中Cu2+浓度达980mg/L,整个过程不需要制乳和破乳。
Extracting and concentrating Copper(Ⅱ) were carried out through gravity separation phase liquid membrane(GSPLM) with P_(204) as carrier and H_2SO_4 as stripping agent. The concentration of Copper(Ⅱ) in external and internal phase could reach to 101ppm and 980ppm, respectively, after the fourth time extraction for the initial Copper(Ⅱ) concentration of 552ppm. Emulsification and demulsification could be ommited.
