  A novel approach has been developed for the determination of two fungicides (diethofencarb and pyrimethanil) in fruit juices by dispersive soild-phase extraction (DSPE) followed by solidification of floating organic drop microextraction (SFODME).In the DSPE step, the fungicides were first extracted from fruit juice into acetonitrile, then PSA sorbent was added into the extraction solvent to remove the matrices.After centrifugation, 1.00 mL supematant was used as the dispersive solvent in SFODME.
