摘要
采用固相萃取 液相色谱 质谱法 (SPE LC MS)对杭州钱塘江流域及杭州地区自来水厂水样中的双酚A进行检测 .在 1 0个采样点均检测出双酚A ,浓度范围在 0 33— 2 5 0 9ng·l- 1 .
A sensitive SPE-LC-ESI-MS method was established to analyze BPA in surface and drinking water.The recoveries for standard spiking surface and tap water were 94.3±3.1,the detection limit of the method was 0.1ng·l -1 .BPA was found in both surface and drinking water from Hangzhou,and its concentration ranged from 0.33 to 25.09ng·l -1 .It should be noted while BPA was only detected in April both in 2002 and 2003,no BPA was detected in July and October,2003,suggesting the temperature related biodegradation of BPA would be a factor for the residue of BPA in raw water.
