Extraction kinetics of zinc by new extractant in ammoniacal systemHUANG Ling(黄玲)1, 2, HE Jing(何静)1, CHEN Yong-ming(陈永明)1, YANG Sheng-hai(杨声海)1, JIN Sheng-ming(金胜明)1, TANG Mo-tang(唐谟堂)1(1. School... area cell. The results show that the extraction rate depends on interfacial chemical reaction and diffusion by using this new extractant to extract zinc, and the apparent activation energy......

Separation of middle rare earths by solvent extraction using 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester as an extractant Loris Pietrelli1,Danilo Fontana1 (1.ENEA, Italian National Agency for New Technologies, Energy and the Environment Via Anguillarese 301, 1-00123 Roma, Italy) Abstract:The extraction of the trivalent middle rare earths from chloride media by kerosene solutions......
solution by predispersed solvent extraction (PDSE) process with extractant (HEHPEHE) and its mixture, including acidic extractant (D2EHPA), alkaline extractant (TOA) and neutral extractant (TBP) were carried out respectively. It is found that the extractant HEHPEHE exhibited high extraction selectivity to chromium(III) from aqueous waste solution. The colloidal liquid aphrons (CLAs) were successfully......
