Preparation and Adsorption Properties of PDMDAAC Modified Bentonite

Abstract:

A novel environmentally friendly water treatment agent was prepared by the natural bentonite and PDMDAAC. The treatment effect of direct black G dyeing wastewater on different preparation conditions was studied. The decoloration rate reached 98.57% under the optimized conditions (cross-linker concentration of 40g/L, M-V of 12 g/L, contact time of 75min, particle size of 0.124mm). The performance characterization of the modified bentonite was observed by means of X-ray diffraction, scanning electron microscopy. The PDMDAAC has entered into the bentonite interplanar space. The adsorption properties of bentonite were improved, which was suitable for the treatment of dyeing wastewater.
