PDMDAAC-attapulgite was prepared by modifying attapulgite with polydimethy ldiallyl ammonium chloride(PDMDAAC),the performance of adsorption,influencing factors and adsorptive effect after regeneration for re- moving trace nitrobenzene from micro-puUuted water by PDMDAAC-attapulgite were investigated.The results showed that the adsorption of trace nitrobenzen by PDMDAAC-attapulgite was better and the removal efficiency to nitroben- zen of the PDMDAAC-attapulgite could reach 73%.PDMDAAC-attapulgite could be ...
