| 中文摘要: |
| 采用固相萃取(SPE)与超高效液相色谱〖CD*2〗串联三重四极杆质谱法(UPLC-MS/MS)测定地下水中雌酮(E1)、17α-雌二醇(α-E2)、17β-雌二醇(β-E2)、雌三醇(E3)、17α-炔雌醇(EE2)、双酚A(BPA)、壬基酚(NP)和辛基酚(OP)等8种典型内分泌干扰物(EDCs),通过优化试验条件,使8种EDCs在0ng/L~1 000ng/L范围内线性关系良好,方法检出限为002 ng/L~017 ng/L。超纯水3个质量浓度水平的加标回收率为799%~999%,测定结果的RSD为22%~71%。将该方法应用于某流域35个地下水样品中EDCs的检测,结果OP、BPA、EE2为主要检出物,检出率分别为100%、771%、943%。 |
| 英文摘要: |
| Eight typical endocrine disrupting chemicals(EDCs), including estrone(E1), 17α estradiol(α E2), 17β estradiol(β E2), estriol(E3), 17α ethinylestradiol(EE2), bisphenol A(BPA), nonylphenol(NP), and octylphenol(OP), were determined in groundwater by solid phase extraction(SPE) and ultra performance liquid chromatography triple quadrupole tandem mass spectrometry(UPLC MS/MS).The experimental conditions were optimized, and the eight EDCs showed good linearity in the range of 0ng/L~1 000ng/L.The method detection limits were 002 ng/L~017 ng/L.The recoveries at three spiked concentration levels in ultrapure water were 799%~999%, with relative standard deviations(RSDs) of 22%~71%.The method was applied to the determination of EDCs in 35 groundwater samples from a basin.OP, BPA, and EE2 were the main EDCs detected, with detection rates of 100%, 〖GK!87mm〗771%, and 943%, respectively. |
