[Determination of bisphenol A in drinking water system components by liquid chromatography-tandem mass spectrometry].
OBJECTIVE
To develope the determination methods for bisphenol A in drinking water system components.


METHODS
30 samples were quantitatively analyzed by liquid chromatography-tandem mass spectrometry (LC/MS/MS).


RESULTS
Bisphenol A was linear in the range 0-100 ng/ml and the linear correlation coefficient reached 0.9994. The minimum detection limit was 5 microg/kg. The spiked recoveries were from 90% to 99%, and the RSD were between 1.8 -5.0%. Bisphenol A was measured in nine out of thirty samples. The detected ratio was 30% and the maximum was 1.82 mg/kg.


CONCLUSIONS
The method was quick, sensitive and specific.
