热处理前后钠长石的结构变化及其对水体中Cd~(2+)的修复实验研究表明:热处理后钠长石的微结构发生了一定的变化,且对常温水体中的Cd~(2+)修复能力明显提高。钠长石修复能力的提高应该与其结构的微小变化关系密切,推测为热处理使钠长石的内部结构发生变化致使架状硅酸盐中阳离子与Cd~(2+)的交换能力增强。与其它温度热处理的钠长石对比,800℃热处理的钠长石有较高的修复能力。
The structural changes of albite before and after heat treatment and their remediation of Cd2 + in water show that the microstructure of albite changed after the heat treatment, and the change of Cd2 + ) Repair ability improved significantly. The improvement of albite repair ability should be closely related to the small change of its structure. It is presumed that the heat treatment causes the change of the internal structure of albite, resulting in the enhancement of the exchange ability of cation and Cd 2+ in the framework silicate. Compared with other temperature-treated albite, 800 ℃ heat-treated albite has a higher ability to repair.
