摘要: 基于气相色谱–三重四极杆质谱联用（GC-MS/MS）技术建立了同时测定水中13种挥发性消毒副产物（V-DBPs）的方法。采用GC-MS/MS鉴别了13种V-DBPs的前级离子和产物离子，优化了色谱和质谱参数，确定了4种典型样品预处理方法（液液萃取（LLE）、静态顶空（SH）、吹扫捕集（P&T）和固相微萃取（SPME））的最优操作参数，对比分析了其准确度和精密度。采用优化后的预处理方法和仪器参数，建立了测定13种目标物的标准曲线。当13种V-DBPs浓度为0.05~100 μg/L时，4种预处理方法对应的方法精密度顺序为：SPME>SH>P&T>LLE。在地表水、地下水和自来水中分别添加2.5和25 μg/L水平的V-DBPs混合标准样品时，4种预处理方法均具有较好的检测精密度，对应的方法准确度顺序为LLE、P&T>SH>SPME。本研究基于GC-MS/MS的检测方法优于现有方法，可满足消毒剂处理后出水中13种V-DBPs的快速、准确测定要求。

Abstract: Thirteen kinds of volatile disinfection by-products (V-DBPs) in water were determined by gas chromatography-triple quadrupole mass spectrometer (GC-MS/MS). GC-MS/MS was used to identify the precursor ions and product ions of 13 kinds of V-DBPs, and the operating parameters of chromatography and mass spectrometry were optimized. The optimal operation parameters of four typical sample pretreatment methods (liquid-liquid extraction (LLE), static headspace (SH), purge and trap (P&T) and solid phase microextraction (SPME) were determined, and their accuracy and precision were compared and analyzed. The standard curves of 13 kinds of V-DBPs were established using the optimized pretreatment method and instrument parameter setting. The results showed that the precision of the method was in accordance with SPME>SH>P&T>LLE when the concentration of 13 kinds of V-DBPs ranged from 0.05 μg/L to 100 μg/L. The four pretreatment methods had good detection precision when 2.5 and 25 μg/L mixed standards of V-DBPs were added to surface water, groundwater and tap water, and the accuracy of the method was in accordance with LLE, P&T>SH>SPME. The detection method based on GC-MS/MS was superior to the existing detection methods, and could meet the needs of rapid and accurate determination of 13 kinds of V-DBPs in discharge water after disinfection.
