P-204(磷酸〈2—乙己基基〉酯)—YW100锗萃取体系的反萃研究

The study on Back Extractant From a Solution of P204-YW100 Containing germanium

本文研究了用1.0mol/LHF作为P204—YW100萃锗体系的反萃剂是行之有效的。该反萃剂的反萃液用N—235(三烷基胺R_3N)对锗进行二次富集,使锗含量达到20g/l,从而为溶剂法生产锗创造了一定条件。并对氢氟酸反萃锗的行为和N—235在萃取过程中的行为进行了讨论。

It Was proved to be effective that 1.0mol/L hydrogen fluoride was Chosen as a back extractant from a solution of P204-YW100 containing germanium. The back extraction solution was further enriched to the concentration of 20g/l in order to suit the production of germanium. The behaviou of hydrogen fluoride in the back extraction of germanium solution and the behaviou of N235 in the enrichment process were also disucssed.
