摘　　要：凹凸棒石是一种含水镁铝硅酸盐材料,具有独特的链层状结构及良好的胶体性质和较高的吸附脱色能力,已被广泛应用于各领域。但因形成地形条件的差异,杂质含量相差较大,若要得到高纯度和性能优良的凹凸棒石,需要进行改性处理。介绍了目前常用的热改性、酸改性、有机改性和其他改性方法等,为后续改性研究提供依据。Attapulgite is a kind of magnesium aluminosilicate material,which has unique chain-layer structure,good colloid property and high adsorption and decoloration ability,it has been widely used in various fields.However,due to the difference in topographic conditions,the impurity content varies greatly,so attapulgite with high purity and excellent performance needs to be modified.In this paper,the commonly used thermal modification,acid modification,organic modification and other modification methods are introduced,which provide a basis for subsequent modification research.
