沸石是一种廉价的、可供实际利用的天然无机离子交换剂。近年来国内已相继开展了天然沸石岩对碱金属、碱土金属、重金属和一些放射性元素的交换性质的研究及在海水提钾、污水处理、硬水软化等方面的应用试验。本文研究的目的是考察我国天然沸石岩对铁的交换能力及除去水中微量铁的可能性。研究结果表明,天然斜发沸石岩经过适当的 Zeolite is a cheap, practical, natural inorganic ion exchanger. In recent years, natural zeolite has been carried out in China on the exchange of alkali metals, alkaline earth metals, heavy metals and some radioactive elements of the nature of research and application in seawater to extract potassium, sewage treatment, water softening and other aspects of the experiment. The purpose of this study is to investigate the exchange capacity of natural zeolite rocks in China and the possibility of removing trace amounts of iron in water. The findings show that natural clinoptilolite rocks are properly applied
