| Abstract: | The purpose of this paper is to study the ability of fly ash to remove CTMAB from wastewater containing cation surfactants CTMAB.The results showed that fly ash modified by the modification reagent of CaO is effective to adsorb CTMAB.Under the experimental conditions of concentration of CTMAB=20～120 mg/L,the amount of the modified fly ash=20～25 g,whose particle size=200～180 mesh and pH=9～13,the removal rate of CTMAB reached about 98%. |
