solvent analysis

A method was described for determination of residues of carbendazim ( MBC) and thiabendazole ( TBZ) in soils. The method involved microwave-assisted solvent extraction ( MASE), liquid-liquid partitioning for cleaning up and analysis by reversed-phase liquid chromatography ( RPLC) with FLD detection.
