The photochemical degradation of Fipronil irradiated by high pressure mercury Lamp (HPML) and sunLight was investigated in this paper. The effects of different types of water, surfactants, pigments,nitrate and nitrite ,metallic ions on the photodegradation of FiproniL in aqueous solution were studied. The main results were summarized as followings:
1.The direct photodegradation rate of Fipronil in aqueous solution or on glass surface by HPML is very quickly, the half-life was only 4.71mi...
