BEHAVIOR OF HERBICIDE BENSULFURON-METHYL IN MICROWAVE-ASSISTED SOLVENT EXTRACTION (MASE) FROM SOILS WITH DIFFERENT PHYSICOCHEMICAL CHARACTERISTICS

The feasibility of MASE application in the determination of Bensulfuron-methyl (BSM) in soils with different organic matter content, consequently with a different capability to adsorb this herbicide is studied. Hydrolysis experiments were performed to check the significance of degradation under vari...
