摘要
概述了Nb、Ta萃取分离机理;对Nb、Ta的常用分光显色剂及适应体系进行了介绍,并对每种体系的显色测定条件、各种测定指标、常见干扰离子及掩蔽剂、生成的络合物组成和稳定情况等进行了介绍;展望了显色剂的发展方向。
In the paper is summarized the Nb/Ta solvent extraction mechanism. Description is made of the common spectrophotometric developer and its applicable system;the determination conditions,various tesring indices, common interfering ions and shelters, resultant complex composition and stability, etc. The future development tendency of the developer is also looked forward,
