沸石是近代的优质无机材料,数十年来在催化裂化、分子筛吸附、气体脱湿以及农业等研究应用中都取得了显著的成就,本世纪七十年代初已被称为“沸石科学”。然而在离子交换方面却被后起的有机交换剂所压倒。直至近十几年来由于科学技术的飞速发展,对耐酸、耐高温及抗辐射的交换材料提出了特殊的要求,以及沸石对碱金属、碱土
Zeolite is a modern high-quality inorganic material. For decades, it has made remarkable achievements in the research and application of catalytic cracking, molecular sieve adsorption, gas desorption and agriculture. Zeolite has been called “zeolite science” in the early 1970s. However, ion exchange has been overwhelmed by the late organic exchangers. Until the past ten years, due to the rapid development of science and technology, special requirements for acid-fast, high-temperature-resistant and radiation-resistant exchange materials have been put forward, and zeolite has been applied to alkali metals,
