摘要
LAS已成为环境污染中最常见的具有代表性的一类有机污染物。天然沸石经活化处理后具有良好的吸附功能。采用十六烷基三甲基溴化铵(HDTMA)对白银沸石进行活化,分析了HDTMA-沸石的制备以及沸石的粒径、用量、反应时间、pH值、LAS浓度,以及共存PO43-对吸附水中的阴离子表面活性剂(LAS)的影响,据此确定了最佳试验条件。并探讨了活化沸石对LAS的吸附机理。
LAS has become the most common and most typical type of organic pollutant in the environmental pollution.Natural zeolite,when activated,has excellent absorptive property.For the baiyin zeolite activated by hexadecyldimethylammonium bromide(HDTMA),the preparation of HDTMA-zeolite and zeolite particle size,consumption,reaction time,pH value,LAS concentration,and the impact by the co-existing PO3-4 on the anionic surfactant(LAS) in the absorbed water is analyzed,and the optimum experimental conditions are accordingly identified.And the mechanism for the absorption of LAS by the activated zeolite is discussed.
