摘要
采用P507为载体的煤油-Span80-P507-HCl组成的液膜体系,研究了自稀土浸出液萃钍萃稀土后的工业废水中回收钍的基本原理,考察了制乳条件、油内比、水乳比、pH值和提取时间等因素的影响。
The extraction of the thorium from the dip solution of rare earth was studied using the liquid membrane emulsion technology by P507. The conditions of making emulsion and the technological factors such as the ratios of oil to inner and water to emulsion, the pH and the extraction time etc. were investigated.
