摘要
本研究用十六烷基三甲基溴化铵与N,N-二甲基十二烷基甜菜碱复配的混合表面活性剂对天然沸石改性,初步研究了改性沸石吸附废水中重铬酸盐和苯酚的影响因素。结果表明:在pH值为68,吸附时间为30min,振荡速度为160r/min时,去除率可达90%以上,为改性沸石处理废水提供了一定的依据。
The intermixture of Cetyltrimethyl Ammonium Bromide and N,N-C12BE was used to modify the natural zeolite. Effect factors of modified zeolite adsorbing bichromate and phenol from wastewater were studied. The results indicate that when the pH value is 6-8, the adsorption time is 30min and the stirring rate is 160r/min, the rate of removing is more than 90%, which offers certain reference for treating wastewater by modified zeolite.
