摘　　要：建立以固相萃取/高效液相色谱法测定水中9种烷基酚类化合物和双酚A的分析方法。方法采用固相萃取富集、净化处理水样,经安捷伦Eclispe XDB-C_(18)色谱柱分离后用荧光检测器检测。实验结果表明,9种烷基酚类化合物和双酚A在0~1000μg·L^(-1)范围内曲线线性关系较好,相关系数均在0.999以上,检出限为0.004~0.009μg·L^(-1)。对0.25、1.00和2.50μg·L^(-1)3个浓度标准样品进行精密度和准确度测试,平行测定7次的精密度和准确度较好,相对误差范围为0.2%~9.6%,相对标准偏差范围为4.4%~11.9%,对实际样品进行3个不同浓度的加标回收率测试,加标回收率在79.8%~115%之间,样品加标回收率较好。A method for determination of 9 alkyl phenols and bisphenol A in water by solid phase extraction/high performance liquid chromatography was established.The water samples were enriched and purified by solid phase extraction,separated by Agilent Eclispe XDB-C_(18)column and detected by fluorescence detector.The experimental results showed that the curves of 9 alkyl phenols and bisphenol A were linear in the range of 0~1000μg·L^(-1),the correlation coefficients were above 0.999,and the detection limits were 0.004~0.009μg·L^(-1).The precision and accuracy of the three concentration standard samples of 0.25μg·L^(-1),1.00μg·L^(-1)and 2.50μg·L^(-1)were tested.The precision and accuracy of the parallel determination for 7 times were better,the relative error range was 0.2%~9.6%,and the relative standard deviation range was 4.4%~11.9%.The recovery rate of three different concentrations of the actual sample was tested.The recovery rate of the sample was 79.8%~115%,and the recovery rate of the sample was good.
