摘要
用液相共沉淀法制备锌铝类水滑石颗粒。在500℃下焙烧类水滑石转化为锌铝复合氧化物,并用XRD、TG/DTA和FT-IR等对类水滑石和锌铝复合氧化物进行表征分析。用锌铝复合氧化物吸附水中的阴离子表面活性剂,对实验条件和主要影响因素进行研究,并对其吸附机理进行了探讨,实验结果表明,锌铝复合氧化物对阴离子表面活性剂去除效果明显。
A hydrotalcite-like compound has been prepared by coprecipitation method. The hydrotalcite-like compound is calcined at 500 ℃,transformed into Zn-Al-O mixed oxide.The hydrotalcite-like compound and Zn-Al-Al-O mixed oxide are characterized by XRD, TG/DTA and FT-IR respectively. The removal of anionic surfactants from aqueous solution by the Zn-Al-O mixed oxide has been investigated. The conditions of the experiment and the influential factors are studied and the adsorption mechanism is discussed. The results show that the Zn-Al-O oxide has remarkable effect on the removal rate of anionic surfactants.
