| Abstract: | A new tandem mass spectrometry method for determination of pentachlorophenol (PCP) in leather was described.The conditions of the method including parent ion m/z 266, excitation voltage 0.8 V, product ion m/z 230 etc.were discussed throughly.The external standard by m/z 230 peak value was used for quantitative determination.The linear range(mg/L),detection limit(mg/kg), recorvery and RSD was 0.1~10.0,0.005, 85. 4% ~ 102. 5%, 2. 6% ~ 3. 6%, respectively.This method was rapid, simple and accurate. |
