基于还原体系的气溶胶中铀同位素分析方法研究

Abstract

Abstract: The analysis of uranium isotopes is of great significance to the radiation dose assessment caused by uranium and the investigation of environmental pollution sources. A procedure for analysis of uranium isotopes in aerosol samples with ascorbic acid as reduction agent was established. The aerosol samples were completely melted. The analytical method had a good removal effect on interfering elements such as iron and plutonium, and the radiochemical recovery rates of uranium isotopes were in the range of 74.5% and 93.6%, with an average of 81.5%, which can meet the requirements of routine uranium isotopes analysis of aerosol samples.

Key words: reduction system, aerosol, uranium isotopes, analysis
