摘要/Abstract

摘要： The microencapsulation of the extractant was studied by drying-in-liquid with a [(O_Ⅰ/W_Ⅰ)/O_Ⅱ]/W_Ⅱ multi-emulsion. The microcapsules were characterized by the release efficiency of the extractants to discuss the effect of Tween 60, gelatin, and EC on the experimental results. The size dispersity of microcapsules with the different concentrations of gelatin was also discussed. The results show that microcapsules with good membrane tension for several extractants can be obtained with this method.
