浮选光度法研究进展

Research progress of flotation spectrophotometry

浮选光度分析法是一种灵敏度高、选择性好的分析方法，具有处理样品量大（0．5—2．0L）、分离系数大（〉10^4）、回收率高（〉90％）、易于实现自动化等优点。常用的方法有：泡沫浮选（离子浮选、沉淀浮选）和溶剂浮选（萃取溶剂浮选、气体溶剂浮选）两种。文章综述了浮选光度法及其在大多数离子的浮选中的应用。

notation technology in the application of analytical chemistry has been rearly 30 years of history, the flotation photometric analysis with flotation separation / enrichment technology is formed. This method is first proposed by Courtot - coupoz and Guerder. This is an analysis method of high sensitivity and good selectivity, with characteristics of dealing a large amount of sample （0.5- 2.0 L）, separation factor （ 〉 104）, high recovery （ 〉 90%）, easy to realize automation. Commonly nsed methods： foam flotation （ion flotation, sedimentation flotation） and solvent flotation （flotation extraction solvent, solvent gas flotation） . It summarizes the application of flotation spectrophotometry in the majority of ions based on the chart method of the flotation method.
