提高分析方法的灵敏度是科学技术发展的需求,因而是分析化学研究的重要方向。催化光度法将灵敏度高,设备价廉等优点集于一体,故颇为人们所注重。本文就催化光度分析法的基本原理,应用近况及发展趋向作扼要介绍。一、基本原理催化光度法的基本原理是用光度法测量受均液相催化加速的某一化学反应的速度,其数值与催化剂浓度存在一定的函数关系(常为线性关系),据此可测定催化剂的含量。选择一个慢的氧化还原反应是方法研究 Increasing the sensitivity of analytical methods is the demand for the development of science and technology and is therefore an important direction of analytical chemistry. Catalytic spectrophotometry will be high sensitivity, low cost and other advantages of equipment in one set, it is quite people pay attention. In this paper, catalytic photometric analysis of the basic principles, application status and development trend for a brief introduction. First, the basic principle The basic principle of catalytic spectrophotometry is the use of photometric method measured by the liquid phase catalytic acceleration of a chemical reaction speed, the value and the concentration of the catalyst there is a certain relationship (often a linear relationship), which can be determined Catalyst content. Choosing a slow redox reaction is a methodological study
