摘要:
针对生活饮用水中多种挥发性有机物（VOCs）的日常监测需求，依据《生活饮用水标准检验方法》（GB/T 5750—2023）对《生活饮用水标准检验方法 第8部分：有机物指标》（GB/T 5750.8—2023）4.2节进行吹扫条件优化及色谱柱选择，建立了一种适用于同时快速测定生活饮用水中56种VOCs的吹扫捕集/气相色谱质谱法。优化后方法测定56种VOCs的可检测线性范围为0.1~100 μg/L，相关系数为0.999 0~0.999 7，各目标物的检出限范围为0.003 7~0.52 μg/L，低、中、高3组加标样（n≥6）的平均回收率为73.0%~118%，相对标准偏差（RSD）均小于10%。该方法线性范围较宽、检出限较低、准确度较高、操作简便，可以推广至大部分实验室，尤其是基层实验室。
Abstract:
This study optimized the purge conditions and selected appropriate chromatographic columns in section 4.2 of Standard Examination Methods for Drinking Water-Part 8: Organic Indices (GB/T 5750.8-2023), to develop a purge and trap/gas chromatography-mass spectrometry method for the simultaneous and rapid determination of 56 volatile organic compounds (VOCs) in drinking water. The method is developed in accordance with Standard Examination Methods for Drinking Water (GB/T 5750-2023), and is designed to fulfill the daily monitoring requirements for various VOCs in drinking water. After optimization, the detectable linear range for 56 VOCs was determined to be 0.1-100 μg/L, with correlation coefficients ranging from 0.999 0 to 0.999 7. The detection limits for each target analyte were found to be between 0.003 7 μg/L and 0.52 μg/L. The average recoveries for low-concentration, medium-concentration, and high-concentration standard samples (n≥6) ranged from 73.0% to 118%, while the relative standard deviation (RSD) was less than 10%. The method features a wide linear range, a low detection limit, high accuracy, and simple operation, making it highly adaptable for implementation in most laboratories, particularly in fundamental research settings.
