超纯材料中痕量杂质的分析方法的研究是目前一项重要的任务,分析化学工作者主要从两方面进行研究,一方面不断提高测定方法的灵敏度、发展新的测定方法,另一方面不断发展各种分离与富集方法,使低浓度的被测物质能够适应目前应用的测定方法的灵敏度。正是在这种分析痕量杂质任务要求下,催化测定法才引起分析化学工作者的注意和研究。关于催化测定法的基本知识,任镇章已作过介绍。本文就催化测定法最近几年,特别是自1960年以来,在痕量杂质分析工作中的应用和进展作一介绍。目前催化法的
The analysis of trace impurities in ultra-pure materials is currently an important task. Analytical chemists mainly study from two aspects. On the one hand, they constantly improve the sensitivity of determination methods, develop new determination methods, and on the other hand, Various methods of separation and enrichment have been developed to adapt the low concentration of the test substance to the sensitivity of the currently used assay methods. It is with this task of analyzing trace impurities that catalytic assays have drawn the attention and research of analytical chemists. About the basic knowledge of catalytic assays, Ren Zhen Zhang has been introduced. This article introduces the application and progress of catalytic assay in trace impurities analysis in recent years, especially since 1960. The current catalytic method
