摘 要:采用干式灰化法将亚麻布样品高温分辩,利用氢氧化钙吸收样品分辩产物氯化氢和氯气,用水溶辩后,采用离子色谱法测定氯离子,计算出样品中氯含量。色谱峰面积与氯离子浓度标准曲线方程为:A=0.0915c-0.0290,线性相关系数R2=0.9988;加标回收率为95.2%~106%;相对标准偏差为3.4%;离子色谱检出限为0.5430mg/L。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
