摘  要：
机械力改性、物理改性和化学改性是凹凸棒石环境矿物材料制备的3种主要改性方法。机械力改性法和物理改性法工艺简单,化学改性法效率高且在实际生产中应用较多,但仅仅依靠一种改性作用目前尚难以满足环境应用领域对凹凸棒石矿物物理性能和化学性能的要求。因此,深入系统地研究凹凸棒石环境矿物的基本性能,揭示环境矿物的净化机理,提出进一步提高环境矿物净化性能的改性工艺,将有利于进一步扩大其应用领域。

摘  要：
Three methods have been mainly used to modify palygorskite in the preparation of environmental mineraological material,namely,mechanical modification,physical modification and chemical modification. Both mechanical modification and physical modification are characterized by simplified technology,and chemical modification has its own characteristic of high efficiency and has more application than the former two,while,just with only one modification method,it is difficult to meet the requirements of physical and chemical capabilities applied to environmental field. Consequently,a deep and systematic research shoule be carried out to improve the basic properties of palygorskite,which could reveal the decontaminaton mechanism of the environmental minerals,thus modification process further increasing purification performance could be put forwad and extend the application field of palygorskite.
