摘　　要：采用C 18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0.500μg/L^100μg/L范围内线性良好,方法检出限为0.04 ng/L^0.8 ng/L,空白水样的加标回收率为61.3%~108%,6次测定结果的RSD为3.8%~18.0%。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~1.5 ng/L,平均加标回收率为71.9%~109%,平行测定结果的RSD<15%。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 0.500μg/L to 100μg/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%.
