摘　　要：SO_(x)、NO_(x)、CO_(x)、挥发性有机化合物和Hg蒸汽通过促成光化学烟雾、酸雨和霾的形成,并构成潜在毒性的风险,直接或间接危害大气环境和人类健康。因此,有效控制和减少这些化学品造成的污染至关重要,为此,开发了几种污染治理方法,其中吸附法是最常见和有效的技术之一。沸石作为一种吸附材料,在减少空气污染方面具有很大的潜力。此外,以粉煤灰为基础的沸石合成可以同时处理空气和固体废物污染。综述了近年来粉煤灰合成沸石的研究进展,并对该方法面临的挑战进行了讨论。So_(x),NO_(x),Co_(x),volatile organic compounds and Hg vapor directly or indirectly endanger the atmospheric environment and human health by promoting the formation of photochemical smog,acid rain and haze and posing the risk of potential to xicity.Therefore,it is very important to effectively control and reduce the pollution caused by these chemicals.Therefore,several pollution control methods have been developed,among which adsorption method is one of the most common and effective technologies.As an adsorption material,zeolite has great potential in reducing air pollution.In addition,zeolite synthesis based on fly ash can deal with air and solid waste pollution at the same time.The research progress of zeolite synthesis from fly ash in recent years is reviewed,and the challenges faced by this method are discussed.
