英文摘要	A method for the determination of fenpropathrin, cypermethrin, fenvalerate, tau-fluvalinate, and bifenthrin residues in Chinese tea using high performance liquid chromatography ( HPLC) with fluorescence detection of a post-elution photoirradiation system has been developed. The pyrethroid pesticides were separated by Hypersil ODS column and eluted using acetonitrile/water with a gradient program. The experimental conditions of post-elution photoirradiation system for fluorescence detection were optimized using laboratory-built photochemical reactor for fluorescence derivation. The optimized conditions were applied to determinate the pyrethroid pesticide residues in Chinese tea samples. Detection limits ( S/N = 3) for pesticide analytes were in the range of 0. 012 similar to 0. 048 mu g/g ( dry weight). Relative standard deviations ranged from 3. 4% to 6. 4% (0. 1 mg/L, n = 8).
