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 CH3 Cl+ ion and Positive Thermal Ionization Mass Spectrometry(PTIMS)based on Cs, Cl~+ ion. The application of chlorine stabiej.,.,.co'pe systems(37C1/35C1)in tracing the source of chlorinated organic pollutants, migration and transformation process was further studied |
