采用碱融法处理样品，用离子色谱法测定抗氧剂300中的氯离子含量。氯离子质量浓度在0.1～60 mg/L范围内与色谱峰面积呈良好的线性关系，r＝0.9982。测定结果的相对标准偏差为0.36%～1.14%（n=6），检出限为0.804μg/g，加标回收率为98.84%～100.90%。该法简便、快速，适合于抗氧剂300中氯离子含量的检测。
採用堿融法處理樣品，用離子色譜法測定抗氧劑300中的氯離子含量。氯離子質量濃度在0.1～60 mg/L範圍內與色譜峰麵積呈良好的線性關繫，r＝0.9982。測定結果的相對標準偏差為0.36%～1.14%（n=6），檢齣限為0.804μg/g，加標迴收率為98.84%～100.90%。該法簡便、快速，適閤于抗氧劑300中氯離子含量的檢測。

The samples were treated with the alkali fusion method,and ion chromatography was used to determine the content of chloride ion in the antioxidant 300. The concentration of chloride ion was linear with peak area in the range of 0.1-60 mg/L with the correlation coefficient of 0.998 2. The relative standard deviations were 0.36%-1.14%(n=6). The detection limit was 0.804μg/g, and the recovery rate was 98.84%-100.90%. The method is simple, rapid and suitable for the detection of chloride ion in the antioxidant 300.
