The results show that by controlling the silica-to-alumina ratio, material ratio, solvent ratio and other preparation conditions, high-quality low-silica-to-alumina ratio X zeolite can be obtained. Through ion exchange experiments, it was found that the zeolite has good selective adsorption properties for ammonium ions and sodium ions. The preliminary adsorption experiment results show that low-silica-to-alumina ratio X zeolite has strong adsorption properties for toluene, with an adsorption capacity of up to 40 mg/g. The research results lay the foundation for further in-depth exploration of the synthesis and application of low-silica-to-alumina ratio X zeolite.【Keywords】low-silica-to-alumina ratio X zeolite; preparation; ion exchange; adsorption properties
