N530-OT-煤油-HCl反萃分散组合液膜体系迁移和分离铜的研究 总被引:3,自引:0,他引:3
The transport and separation of copper(Ⅱ) from waste water by a N530-OT-kerosene-HCl strip dispersion hybrid liquid membrane system was studied. The influence of penetrant OT, N530 concentration, pH in feed phase, membrane area, HCl concentration in stripping phase, and volume ratio of membrane phase to stripping phase on transport and separation were also investigated. The experiments demonstrate that Cu(Ⅱ) can be transported selectively from the binary Cu(Ⅱ) and Fe(Ⅲ) solution to stripping phase and that the transport percentage of Cu(Ⅱ) exceeds 93.8% and Fe(Ⅲ) is only 1.8% after transport of 6 hours. 相似文献
