Research on the Modification of Attapulgite Clay
摘要
Abstract
Attapulgite unique crystal form fibrous or rod-like crystal structure of chain and layer it with large surface area, which has a special physical and chemical properties, including adsorption, ion exchange, rheology, catalysis and plasticity. However, because of natural attapulgite different origin and composition contain more impurities seriously affect the good performance of attapulgite. The study found that using the method of purification can be modified attapulgite remove impurities in the channel to increase its surface area, thereby increasing the adsorption and ion exchange properties; with heat-activated, acid, alkaline, organic modifier, modified inorganic, attapulgite modified the original hybrid method can make it porous, surface area increases, the adsorption performance will be improved, and thus modified their higher social and economic benefits.关键词
