A high performance liquid chromatography(HPLC) method has been developed for the simul-taneous determination of residues of eleven triazine herbicides in vegetable. Triazine herbicides were extracted from vegetable with water/methanol and cleaned up with solid-phase extraction cartridges. Then triazine herbicides extracted were analyzed by HPLC with ultraviolet and mass spectrometric detection. The pre-treatment method of sample and chromatographic conditions of analysis were critically examined in this work. The linear ranges for the 11 triazine herbicides were 0.02×10-6~1.0×10-6 g/mL, with correlation coefficients of 0.998 7~0.999 9. The average recoveries for the eleven triazine herbicides in spiked vegetable were in the range of 72.1% to 101.0%, and the relative standard deviations were between 1.2% and 5.1%. The method developed is easy and fast, and has a better purification effect. It can meet the requirement for simultaneous determination of many herbicides in vegetable.
