固相萃取-高效液相色谱-荧光检测法同时测定水中的壬基酚和双酚A

Simultaneous determination of nonylphenol and bisphenol A in water by solid-phase extraction-high performance liquid chromatography-fluorescence detector

利用C18固相萃取柱富集和净化水样，采用高效液相色谱分离、荧光检测建立了水中的壬基酚（NP）和双酚A（BPA）的测定方法，并成功用于污水处理厂各处理单元出水的测定。不同加标水平的NP和BPA的回收率为95．3％～98．6％．其相对标准偏差为2、5％～3．7％。

A comprehensive analytical method based on high performance liquid chromatography-fluorescence detection （HPLC- FLU） has been established for the determination of nonylphenol （NP） and bisphenol A （BPA） in water. Clean-up of the water samples was performed on an C18 solid extraction cartridges （3 mL, 500 mg）. The method was successfully applied to the investigation of residual nonylphenol and bisphenol A in the treated water from different unit operations units of the wastewter treatment plant. Recoveries for nonylphenol and bisphenol A at different spiked levels were ranged from 95.3 % to 98.6 % with relative standard deviations of 2.5 % - 3.7 %.
