Sorption of diuron, atrazine, MCPA, and paraquat on bentonite, humic acid and peat


, : Sorption of diuron, atrazine, MCPA, and paraquat on bentonite, humic acid and peat. Fresenius Environmental Bulletin 5(3/4): 178-184

The sorption of diuron, atrazine, MCPA and paraquat by bentonite and commercials humic acid and peat were studied in batch experiments. The K1 values range between 74.1 mg.kg-1 (MCPA-peat) and 2.38x10superscript 3 mg.kg-1 (paraquat-humic acid) for sorption of herbicides on organic samples, and between 0.17 mg.kg-1 (MCPA) and 55.3x10superscript 3 mg.kg1 (paraquat) for sorption on bentonite.
