Abstract: The migration of two UV absorbents namely benzophenone (BP) and 1-hydroxycyclohexyl phenyl ketone (HCH) from microwave paper to Tenax in microwave oven at the heating power of 100 w, 250 w, 440 w and 600 w was investigated respectively by high performance liquid chromatography(HPLC). In order to study the influence of different heating modes, the migration was also conducted under constant temperature heating. The results showed that the maximum migration of BP at the heating power of 250 w and 440 w is approximate and that of HCH at the heating power of 440 w and 600 w is approximate. In addition, the maximum migration rate of microwave heating was lower than that of constant temperature heating. We can know that temperature and work were also affected on migration under microwave heating in addition to heating power. And microwave heating can better promote the migration of these two compounds, but the maximum migration rate of microwave heating was lower than that of constant temperature heating.
