【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。更多还原

【Abstract】 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^-.更多还原
