摘要
本文介绍了中国沸石的种类及其分布概况,以产自甘肃省白银市的斜发沸石为研究对象,对其化学组成及分子晶格形式作了较为详尽的阐述,经实验室检测出其化学组成及物化指标,且对沸石作为吸附剂、离子交换剂、催化剂处理废水的作用机理进行了深入的探讨,对于天然沸石改性进行了实验研究,得出采用氯化钠溶液对天然沸石改性的效果比较理想,改性溶液的最佳浓度为0.9mol／L,研究沸石在沸水处理领域中的应用,分析了沸石处理各类废水的机理,并对沸石处理废水的前景进行了展望。
The article introduced the type and distribution condition of zeolite in China. Taking the zeolite that comes from Baiyin Gansu province for example, the auther had made a more exhaustive elaboration to chemical composition and the molecular lattice form of zeolite through experiment and its application in water treatment. In the experiment, the author obtained that the best solution to modify nature zeolite was NaCl, the most suitable density was 0.9mol/L. The mechanism of zeolite in water treatment was also analyzed. The prospect of zeolite was pointed out as well.
