摘要

本文以乌海地区的煤矸石为原料，采用传统的水热合成法，在钠钾体系中合成了LSX沸石。对合成产物进行了XRD、SEM、TEM、BET、IR等表征。利用合成的LSX沸石对含Zn 2+和Ni 2+的模拟废水进行吸附，确定了最佳吸附条件。在此条件下，对Zn 2+、Ni 2+的去除率和吸附量分别为96.36%、96.83%、96.36、72.62 mg/g。吸附饱和后的沸石在6% NaOH和1% NaCl作为再生剂的混合溶液中可循环4次，再生率在90%以上。

Preparation of Coal Gangue Based LSX Zeolite and Its Application for Zn²⁺ and Ni²⁺ Adsorption

In this paper, LSX zeolite was synthesized in a sodium-potassium system through the traditional hydrothermal synthesis method with coal gangue in Wuhai area as raw material. The synthesized products were characterized by XRD, SEM, TEM, BET, IR and so on. The synthetic LSX zeolite was utilized to adsorb simulated wastewater containing Zn 2+ and Ni 2+ , and the optimal adsorption conditions were determined. The removal rate and adsorption capacity of Zn 2+ and Ni 2+ were studied under these conditions, which were 96.36%, 96.83%, 96.36, 72.62 mg/g, respectively. The zeolite after adsorption saturation can be recycled 4 times in the mixed solution of 6% NaOH and 1% NaCl as the regenerant, and the regeneration rate is above 90%.
