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.
