含氯有机污染物中氯同位素测定方法及应用进展
Progress in Analytical Methods for Chlorine Isotopes in Chlorinated Organic Contaminants and Application
【摘要】 本文综述了四种稳定氯同位素的测定方法。重点比较了当前使用最为广泛的两种测定方法,基于CH3Cl+离子的正电离气体质谱法(PEIMS)和基于Cs2Cl+离子的正热电离质谱法(PTIMS)。论述了稳定氯同位素体系(37Cl/35Cl)在含氯有机污染物来源、迁移及转换过程中的应用研究。
【Abstract】 Four kinds of measurement methods for stable chlorine isotopes were described in this paper. It focuses on comparison of the most currently widely used two methods,Positive Electron Ionization Mass Spectrometry (PEIMS) based on CH3Cl+ ion and Positive Thermal Ionization Mass Spectrometry (PTIMS) based on Cs2Cl+ ion. The application of chlorine stable isotope systems (37Cl/35Cl) in tracing the source of chlorinated organic pollutants,migration and transformation process was further studied.
