| Abstract: | In order to explore the migration of biphenol A from polycarbonate milk bottles to foods,polycarbonate milk bottles were soaked in four food simulants such as distilled water,3% acetic acid solution,15% ethanol solution and olive oil for 3 days and the content change of biphenol A in the food simulants after 1,2 and 3 days of soaking was detected by high performance liquid chromatography using an external standard method.The recovery rate,accuracy and linear relationship of the developed method were studied... |
