本文研究了巯基环烷酸对镧、钕、钐的萃取性能,发现其萃取能力比环烷酸强,应用酸度范围广,且能避免乳化,可望成为工业萃取剂。
In this paper, the extraction performance of lanthanum, neodymium and samarium by mercapto naphthenate was studied. It was found that the extraction ability of mercapto naphthenate was stronger than that of naphthenic acid, the range of acidity was wide, and emulsification could be avoided. It is expected to become an industrial extractant.
