【摘要】 基于超声提取与固相萃取技术,建立了沉积物和污泥中合成麝香与有机磷酸酯增塑剂/阻燃剂联合前处理方法,并采用气相色谱-质谱对目标化合物进行定性定量分析。考察了不同溶剂对目标化合物萃取效率的影响,确定以丙酮与乙腈-水（1∶3）的组合作为超声萃取溶剂。研究了基质效应和老化效应对目标化合物回收率的影响。结果表明,不同加标浓度下,4种常见合成麝香和9种常用有机磷酸酯的回收率为（27%±12%）^117%±9%。更多还原

【Abstract】 A rapid method was developed for the simultaneous determination of synthetic musks and organophosphate esters( OPs) in sediment / sludge, based on ultrasonic-assisted extraction, solid phase extraction( SPE) and the subsequent analysis by gas chromatography- mass spectrometry( GC- MS). In this study,different solvents were investigated and optimized,and thus acetone and acetonitrile- water( 1 ∶ 3) were chosen for the extraction of analytes. Two potential factors( the matrix effect and aging effect) influencing recoveries of the target compounds of the analgtes were also studied. Under the optimized conditions,13 analytes including 9 widely used OPs and 4 synthetic musks were extracted and analyzed,and the results indicated that acceptable recoveries of the analytes were achieved in the range of( 27% ± 12%)-( 117% ± 9%),from sediment,sludge and pre-extracted sediment at different spiked concentrations.更多还原
