HPTLC Determination of Pyrethroid Residues in Vegetables

Residues of three pyrethroids in spiked vegetables have been analyzed by HPTLC with two mobile phases in a twin-trough chamber and in horizontal chambers. The spots were detected at λ = 203 nm and the greatest detection sensitivity for the three pyrethroids was 10 ng. Recovery after fortification at 0.5-5.0 mg kg-1 was from 70.20 to 108.5%. The relative standard deviation was 1.59-27.94%.
