Abstract

In this study, the elimination of Uranyl from aqueous solution is studied using an advanced technique of extraction; emulsion liquid membrane (ELM). Experimental results for the extraction of Uranyl are presented. The membrane phase consists of Kerosene as a diluent, Cyanex 302 as a carrier and sorbiton monooleate (Span 80) as a surfactant. Sulfuric acid solution as an internal aqueous phase. At the optimum conditions, the main variables studied which influenced the ELM extraction of Uranyl were the concentration of surfactant (3%), carrier (0.3%), internal phase (1 N H2SO4), types of internal phase (H2SO4 sulfuric acid), diluent (Kerosene), stirring speed (200 rpm), and the effect of volume ratios of the internal phase to the organic phase 1:1 (A/O) and of the emulsion to the feed solution 20/200 (Vemul/Vext). The results indicate that the removal percentage was obtained 100% in less than 20 min.This study also evaluated the effect of H2SO4 concentration in the internal aqueous phase on the stripping of Uranyl. The ELM treatment process represents a very interesting advanced separation process for the removal of Uranyl from aqueous solutions.

乳状液膜法提取水溶液中铀酰

本研究采用先进的萃取技术对水溶液中铀酰的去除进行了研究；乳液液膜（ELM）。介绍了萃取铀酰的实验结果。膜相由作为稀释剂的煤油、作为载体的Cyanex 302和作为表面活性剂的山梨醇单油酸酯（Span 80）组成。作为内部水相的硫酸溶液。在最佳条件下，表面活性剂（3%）、载体（0.3%）、内相（1 N H2SO4）、内相类型（H2SO4-硫酸）、稀释剂（煤油）、搅拌速度（200 rpm）以及内相与有机相的体积比为1:1（A/O）和乳液与进料溶液的体积比20/200（Vemul/Vext）的影响。结果表明，在不到20分钟的时间内，去除率达到100% min。本研究还评估了内部水相中H2SO4浓度对铀酰汽提的影响。ELM处理工艺代表了一种非常有趣的从水溶液中去除铀酰的高级分离工艺。
