摘要:
摘要:利用各类改性技术提高非金属矿物的吸附效果成为近年来的研究热点。文章基于非金属矿物资源分布广、储存量大、可再生活化重复利用及具有表面吸附作用、离子交换作用等特点,将其应用于废水中金属离子的去除;文章阐述了不同非金属矿物的性质、结构,分析了其改性方法—内部改性法和表面改性法,通过对沸石、蒙脱土、粉煤灰等几种典型的非金属矿物不同改性方法的对比分析,阐明了利用酸、碱、盐及有机物等改性后的非金属矿物对不同重金属离子的吸附效果及影响因素,展望了非金属矿物改性技术的应用前景和发展趋势。
Abstract:
Various modification technologies are used to improve the adsorption effect of nonmetallic mineral has become a research hotspot in recent years. . Based on the properties of wide distribution,large storage, reusability, and surface adsorption and ion exchange ability, nonmetallic mineral can be used to remove metal ions from wastewater. This paper discusses different properties and structure of nonmetallic minerals, and summarizes their modification methods including internal modification methods and exterior modification methods. Through the analysis of different modification methods of several typical nonmetallic mineral like zeolite, bentonite and flyash, this paper also studies the heavy metal ion adsorption effect of nonmetallic mineral modified by acid, alkali, salt and organic matter and its influence factors, and prospects the development trend of nonmetallic mineral modification technology.
