摘要：
The preparation of composite bentonite that natural sodium bentonite as raw material and CTMAB/CPAM as modifier.The best preparation conditions: CTMAB dosage 5mmol, CPAM dosage 0.03g, original soil dosage 4g, stirring speed 300r/min, the modified time islonger than 2h. It is showed that CTMAB and CPAM had entered the interlayer by SEM and XRD characterization of the composite modified bentonite.Decolorization rate above 95% when dealing with acid red, direct fast black and basic fuchsin three kinds of dyes by composite bentonite.Kinetic results show that quasi-two kinetic model can describe composite bentonite material ofye wastewateradsorption process.
