摘要
采用胶囊化技术制备出内含伯胺(N1923)的海藻酸铈胶囊.考察了其在硫酸介质中萃取铈的传质动力学.实验结果表明,水相中铈溶液的酸度不影响渗透系数,胶囊萃取Ce3+的速率大于萃取Ce4+的速率.
Encapsulation has been used to prepare the capsule of cerium alginate which contain N1923, and the transferring kinetics of the extraction of Ce in H2SO4 has been studied. The experimental results show that the acidity of Ce solution doesn't affeet the permeable coefficient, and the extraction rate of Ce(Ⅲ)is faster than that of Ca(Ⅳ).
