摘要
以粉煤灰作为吸附剂 ,研究了含阳离子表面活性剂CTMAB为 2 0～ 12 0mg L的模拟废水去除CTMAB的一般规律。研究结果表明 ,以CaO为改性剂改性的粉煤灰对含阳离子表面活性剂废水具有良好的吸附性能 ,在含CTMAB浓度为 2 0～ 12 0mg L ,改性粉煤灰用量每 2 0 0mL为 2 0～ 2 5g,粒径范围 2 0 0～ 180目 ,pH为 12～ 13的实验条件下 ,CTMAB的去除率最高可达
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%.
