A Review on the Modification and Applications of Attapulgite Clay

Owing to its unique fiber-like morphology and microporous channel-like crystalline structure with high surface area,attapulgite clay mineral has a wide range of industrial applications derived from its adsorbent,decolourized,rheological and catalytic properties.After a simple introduction of the mineralogical structure and chemical composition of the attapulgite clay,as well as its physico-chemical properties,this paper reviewed some modification methods,such as thermal,acid,alkali and organo-mineral treatm...
