丝光沸石的合成及其在磷酸净化中的应用

摘要

丝光沸石具有发达的空隙通道,其堆叠、扭转,急剧增加了其比表面积并提高其吸附性能.湿法磷酸中的重金属较难处理,如采用沉淀法会引入部分离子,使磷酸的纯净度降低,应用丝光沸石的吸附性能进行处理有明显的效果且丝光沸石可以重复利用.%Mordenite has a well-developed gap channel, which stacks and twists sharply increases its specific surface area and improves its adsorption performance. It is difficult to treat heavy metals in wet process phosphoric acid, for example, the introduction of some ions by precipitation method can reduce the purity of phosphoric acid, and the adsorption performance of mordenite has obvious effect, and mordenite can be reused.
