| Abstract: | Two organobentonites were synthesized by placing quaternary ammonium surfactants such as cetyltrimethylammonium bromide (CTMAB) and cetylpyridinium oh loride (CPC) on bentonite. They were then examined for their ability to adsorb nitrobenzene. The equilibrium for organobentonites to adsorb nitrobenzene is quickly reached. The saturation adsorbing capacities of CPC-bentonite or CTMAB-bentonite for nitrobenzene are 87. 6 mg/g and 117. 0 mg/g, respectively. The removal rates for two organobentonites to treat nitrobenzene in wastewater are 4-5 times for the original mineral. |
