摘　　要：在介绍再生酸净化方法的基础上,比较了外掺沉淀吸附法和萃取吸附法,指出,两种方法的净化效果基本相同,但在工业生产中,外掺沉淀吸附法的经济效益明显好于萃取吸附法。On the basis of introducing the purification method of regenerated acid, the external-mixing sedimentation adsorption method and extraction adsorption method are compared, it points out that the purification effects of both methods are almost the same, but in the industrial production, the economic benefit of external-mixing sedimen-tation adsorption method is obviously better than that of extraction adsorption method.
