| 中文摘要: |
| 采用C18柱固相萃取(SPE)-三重四级杆气相色谱-质谱法同时测定水中18种含有机氯的环境内分泌干扰物，方法在0500 μg/L~100 μg/L范围内线性良好，〖JP3〗方法检出限为004 ng/L~08 ng/L，空白水样的加标回收率为613%~〖JP〗108%，6次测定结果的RSD为38%~180%。将该方法用于饮用水源水监测，18种目标化合物的测定值为未检出~15 ng/L，平均加标回收率为719%~109%，平行测定结果的RSD＜15%。 |
| 英文摘要: |
| A method for determining 18 kinds of environmental disrupting chemicals（EDCs）in drinking water source by solid phase extraction （SPE） gas chromatography triple quadrupole mass spectrometry （GC MS/MS） was established. The method had a good linearity in the range of 0.500 μg/L to 100 μg/L， the detection limits ranged from 0.04 ng/L to 0.8 ng/L， the recoveries of spiked samples on blank were from 61.3% to 108%， and the RSDs of the results by 6 times repeated measurement were from 3.8%~18.0%. When applying this method in monitoring the source of drinking water， the measurements of these 18 target compounds were from not detected to 1.5 ng/L， the average recoveries were from 71.9% to 109%， the relative standard deviations （RSDs） were less than 15%. |
