摘要	A method using dry ashing combined with triple. phase ion. exchange chromatography was developed to enrich chlorine in the plant, which could eliminate the effect of organic impurities on the determination of chlorine isotope by thermal ionization mass spectrometry. In the procedure, the recoveries indicated that there was no loss of chlorine and no fractionation of chlorine isotopes occur. The results showed that the composition of chlorine isotope in the tissues of plants in Qinghai-Tibet Plateau area and Shandong area ranged from -1.79 parts per thousand to +4.77 parts per thousand with an average of 1.20 parts per thousand. delta Cl-37 values of the two plant samples in Shandong area not more than 0 parts per thousand indicated that Cl-35 was enriched in the organs of the two plants and. delta Cl-37 values in Qinghai-Tibet Plateau area more than 0 parts per thousand indicated the deficiency of Cl-35. Chlorine isotope composition fractionated significantly in the plant samples or in different tissues of a plant. This may be caused by the differences of the medium where the plants grow, the transport of chlorine or the physiological effect in the uptake of chlorine by plants, which put forward a new insight for the further investigation of chlorine behavior in plant and the global cycling of chlorine in the biogeochemistry.
