摘要
采用十六烷基三甲基溴化铵(CTAB)和聚丙烯酰胺(PAM)改性高岭土,研究其对模拟脂肪醇聚氧乙烯醚(AEO-9)/对硝基苯酚废水中对硝基苯酚的吸附行为。结果表明,单一对硝基苯酚在有机高岭土上的吸附与溶液pH和对硝基苯酚溶液浓度密切相关;在二元体系中,溶液中共存AEO-9会降低有机高岭土对对硝基苯酚的吸附效果,对硝基苯酚与AEO-9产生竞争吸附,竞争作用的大小与溶液中对硝基苯酚与AEO-9的浓度比以及有机高岭土对污染物的吸附机制有关。
Using CTAB and polyacrylamide modified Kaolin,study its effect on the analog（AEO-9）/nitrophenol wastewater on the adsorption of p-nitrophenol behavior. The results show that organic Kaolin adsorption of p-nitrophenol is closely related to the pH and concentration of p-nitrophenol in single solution of p-nitrophenol; in the binary system,the solution coexist AEO-9 will reduce organic Kaolin adsorption of p-nitrophenol,p-nitrophenol and AEO-9 generates competitive adsorption competitive,the competitive size is related to the solution of p-nitrophenol and AEO-9 Kaolin concentration ratio and organic pollutants adsorption mechanisms.
