摘要	A simple technique using the combination of dynamic and static cation-exchange was used to enrich and purify Cl from the liquid samples, especially from rainwater with low concentration of chlorine. The recovery of Cl is better than 97%. The process is suitable to the isotopic analyses of Cl by positive thermal ionization mass spectrometry based on the measurement of [Cs2Cl](+) ion with graphite load. The measured results of Cl isotopic composition show that the visible isotopic fractionation of chlorine was not took place during chemical process. The procedure of chlorine separation and its isotopic measurement provides a possibility for the study of Cl isotopic geochemistry in low-concentration liquid sample.
