建立了水中8种双酚-二环氧甘油醚（双酚 A 二缩水甘油醚（BADGE）及其衍生物双酚 A（3-氯-2-羟丙基）甘油醚（BADGE·HCl）、双酚 A双（3-氯-2-羟丙基）醚（BADGE·2HCl）、双酚 A（2，3-二羟丙基）甘油醚（BADGE· H2O）、双酚 A双（2，3-二羟丙基）醚（BADGE·2H2O）、双酚 A（3-氯-2-羟丙基）（2，3-二羟丙基）醚（BADGE·HCl ·H2O）和双酚 F-二环氧甘油醚（BFDGE）及其衍生物双酚 F 双（3-氯-2-羟丙基）醚（BFDGE·2HCl））的固相萃取-高效液相色谱-串联质谱（ SPE-HPLC-MS/MS）测定方法。10个饮用水接触涂料样品在室温避光条件下，以超纯水浸泡（24±1）h，然后取200 mL经 C18固相萃取柱进行净化浓缩，以 C18色谱柱进行分离，以5 mmol/L醋酸铵、甲醇和水为流动相进行梯度洗脱，质谱多反应监测（ MRM）模式检测，外标法定量。结果表明，8种双酚-二环氧甘油醚在0.007~5.00μg/L线性关系良好，相关系数均大于0.9990，该方法对8种双酚-二环氧甘油醚的定量限为7~91 ng/L，回收率为79.1％~101％，RSD为4.0％~12％。该方法具有灵敏度高、选择性强的特点，能够满足水中双酚-二环氧甘油醚的快速检测和准确定量。

A solid phase extraction coupled with high performance liquid chromatography-tandem mass spectrometry( SPE-HPLC-MS/MS)method was developed for the determination of eight bisphenol diglycidyl ethers,including bisphenol A diglycidyl ether( BADGE),bisphe-nol A(3-chloro-2-hydroxypropyl)glycidyl ether(BADGE·HCl),bisphenol A bis(3-chloro-2-hydroxypropyl)ether( BADGE · 2HCl),bisphenol A( 2,3-dihydroxypropyl) glycidyl ether (BADGE·H2O),bisphenol A bis(2,3-dihydroxypropyl)ether(BADGE·2H2O),bisphenol A (3-chloro-2-hydroxypropyl)(2,3-dihydroxypropyl)ether(BADGE·HCl·H2O),bisphenol F diglycidyl ether( BFDGE ) and bisphenol F bis( 3-chloro-2-hydroxypropyl ) ether( BFDGE · 2HCl)in water. A total of ten samples were collected from the leaching of the coatings for drinking water supply system. Then,200 mL exposure water was preconcentrated on C 18 solid-phase extraction cartridge. The eight compounds were analyzed by liquid chromatography-tandem mass spectrometry method on a C 18 column by the gradient elution with methanol, water and 5 mmol/L ammonium acetate as mobile phases in the multiple reaction monitoring ( MRM)scan mode. The external matrix standard solutions were used for the quantitative deter-mination and the calibration curves of the eight compounds showed good linearity in the range of 0. 007-5. 00 μg/L with the correlation coefficients more than 0. 999 0. The limits of quantifi-cation( LOQs)of the method were 7-91 ng/L. The spiked recoveries ranged from 79. 1% to 101% with the relative standard deviations of 4. 0%-12%. The method is sensitive and accurate, and is applicable to the determination of bisphenol diglycidyl ethers in water.
