摘要
本文研究了一种简便、易行、快速的方法,能从稻壳内提取高纯度 SiO_2.我国水稻产量居世界第一位,折算成稻壳年产量约四千万吨.这将是大规模生产高纯度 SiO_2的廉价原料.本法是使稻壳处于水溶液环境中,在高压下用高能态的活性氧氧化稻壳,从而获得高纯度 SiO_2.本法还适用于所有植物体内 SiO_2提取.这不仅便于研究 SiO_2在植物体内的作用,同时还可以从植物体内去寻找一些具有特殊性能的 SiO_2.
This thesis studies a simple,feasible and quick method to extract high-purity.SiO_2 fromrice husks.The production of rice in China ranks the first in the world,and the output of ricehusks is about 40 million tons per year,which will be the cheap raw materials to produce high-purity SiO_2 in a large scale.High-purity SiO_2 can be obtained by oxidizing rice husks in a aqueous solution under highpressure with high-energy active oxygen.This method is suitable for extracting SiO_2 from all kinds of plants as well,which is helpfulnot only for the study of the function of SiO_2 inside the plant,but also for the approach offinding out some SiO_2 with special properties in plants.
