摘要

摘要: 建立了高效液相色谱-电感耦合等离子体质谱（HPLC-ICP-MS）测定包装饮用水中溴酸盐的方法。比较了HPLC-ICP-MS法与离子色谱法测定溴酸盐的检出限、准确度和精密度，并用这两种方法同时分析了20份实际水样品中溴酸盐的浓度。结果表明：HPLC-ICP-MS法在1.0~50.0 μg/L范围内线性关系良好，相关系数R为0.999 9，检出限为0.048 μg/L，回收率为96.8%~104.9%；离子色谱法在10.0~200.0 μg/L范围内线性关系良好，相关系数R为0.999 2，检出限为2.0 μg/L，回收率为85.6%~101.3%。两种方法测定结果的一致性较好，且准确度和精密度均符合方法学要求。但比较而言，HPLC-ICP-MS法的检出限更低、灵敏度更高、准确度和精密度更好、分析速度更快，更适用于包装饮用水中低浓度溴酸盐的常规检测。

Abstract: The method for determination BrO^-₃ in packing drinking water by high performance liquid chromatography coupling with inductively coupled plasma mass spectrometry (HPLC-ICP-MS) was developed. The detection limit, accuracy and precision of HPLC-ICP-MS and ion chromatography were compared. And the two methods were employed to determine BrO^-₃ in 20 packing drinking water samples. The HPLC-ICP-MS shows good linearity within 1.0-50.0 μg/L with the correlation coefficient (R) 0.999 9. The limit of detection is 0.048 μg/L and the recovery is 96.8%-104.9%. The ion chromatography shows good linearity within 10.0-200.0 μg/L with the correlation coefficient (R) 0.999 2 as well. The limit of detection is 2.0 μg/L and the recovery is 85.6%-101.3%. The two methods show good accuracy, precision and consistency. Moreover, in comparison to ion chromatography, the HPLC-ICP-MS was found to be more sensitive, selective and rapid, especially suitable for the routine analysis of low concentration bromate in packing drinking water.
