Open publisher page 0 citations

Abstract

Modified organobentonite were synthesized by placing quaternary ammonium salt cationic surfactants cetyltrimethylammonium bromide(CTMAB)and anionic surfactants sodium dodecyl benzene sulfonate(SDBS)on Na-bentonite.The adsorption effect,mechanism and influence factors for modified bentonite to adsorb pesticide carborfuran of carbamate in water were investigated.Results indicated that organic carbon content and dosage of modified bentonite affected removal rate of adsorption of modified bentonite to carbofuran.Surfactants entered into bentonite by intercalation,and expanded the layers of bentonite in effect,organic intercalation had an obvious result.100CTMAB-10SDBS bentonite was the best modifier,with the best dosage of soil 20.00 g/L,adsorption equilibrium time 3 h and removal efficiency 92.60%.Adsorption behavior of modified bentonite was in accordance with Freundlich model,with correlation coefficient of deformation formula above 98%.
