| Abstract: | Flax cloth was decomposed in high temperature by dry ashing method. The sample decomposed produced hydrogen choloride and chlorine gas which were absorbed by calcium hydroxide, then the absorbent was resolved in water. Chlorine ion was determined by ion chromatography and the content of chlorine in the sample was calculated from the concentration of chlorine ion in the absorbent solution . The standard curve was A = 0.091 5C - 0.029 0 （ A ： chromatography peak area of chlorine ion, C ： concentration of chlorine ion in the absorbent solution） , The linear correlation efficient（ R2 ） was 0.998 9. The relative standard deviation （RSD） was 3.4%, recoveries were 95.2% - 106%, and the limit of detection of chlorine ion was 0.543 0 mg/L |
