Process for selectively recovering Ge and as from aqueous solutions |
摘要 |
A process for extracting germanium and/or arsenic from an aqueous solution is described. In order to increase the yield and to perform a highly specific separating process, the liquid membrane technology is employed, in which the starting solution is adjusted by means of hydrochloric acid to a concentration in excess of 6 and up to 10 moles HCl/1, a polyisobutylenesuccinic anhydride/polyamine condensation product is used as a surfactant in the organic outer phase of the liquid membrane emulsion is adjusted to a pH value from 0 to 14 while a supply of chlorine ions is precluded.
