摘要
建立了超声辅助-分散液相微萃取/高效液相色谱测定沉积物中双酚A,四溴双酚A,四溴双酚A双烯丙基醚,四溴双酚A双（2,3-二溴丙基）醚的方法。对萃取剂与分散剂的种类与用量、超声时间、盐效应及p H等萃取条件进行了优化。在优化的条件下,此方法的线性范围为0.1~100 mg/L,线性相关系数（r）为0.9996~0.9999。样品平均回收率为83%~91%,相对标准偏差为1.8%~4.9%。检出限（S/N=3）为0.01~0.15μg/L。方法可用于实际水库沉积物中双酚A及其衍生物的测定。
A method of ultrasound-dispersive liquid-liquid microextraction（ US-DLLME） combined with highperformance liquid chromatography（ HPLC） has been developed for rapid determination of bisphenol A（ BPA）,tetrabromobisphenol A（ TBBPA）, TBBPA-bis（ allyl ether）（ TBBPA-BAE） and TBBPA-bis（ 2,3-dibromopropyl ether）（ TBBPA-BDBPE） in sediment. Experimental conditions of DLLME such as the type of extraction solvents and dispersive solvents,their volume,ultrasonic time,p H and ionic strength of the sediment samples were optimized. The results showed that analytes had linear responses between 0. 1 and 100 mg/L,with linear correlation coefficient（ r） of 0. 9996 ~ 0. 9999. The limits of detection were 0. 08,0. 01,0.10,0. 15 μg/L,respectively. The average recoveries of spiked sediment samples were 83% ~ 91%,and the relative standard deviations were 1. 8% ~ 4. 9%. The developed method is simple and environmentally friendly for the determination of bisphenol A and its main derivatives in sediment samples.
