摘　　要：采用电炉加热、灼烧分解浓过氧化氢、C18过滤有机物,去除干扰后,用离子色谱法测定了强碱性BHP废液中氯离子浓度。采用AS14分离柱,用Na2CO3/NaHCO3淋洗,流速为1.2mL/min,成功测定了废液中Cl-的含量,检出限为0.072mg/L,加标回收率为98.2～99.9%。并与传统的重量法测定结果进行了对比,结果比较满意。Ion-chromatographic procedure was described for the determination of Cl^- in basic hydrogen peroxide. Separation was performed with Na2CO3/NaHCO3 as mobile phase at a flow rate of 1.2mL/min. The separation of Cl^- was accomplished with a Dionex IonPac AS14 column. The analysis was completed in 5min, the limit of detection for Cl^- was 0.072 mg/L, and the recoveries were 98.5% - 99.9%. Good results were achieved for determination of Cl^-. The method was characterized by rapidity, sensitivity and simultaneous determination of Cl^-.
