Research Progress on Physical and Chemical Properties of Attapulgite Clay
摘要
Abstract
Attapulgite clay has adsorption, carrier, cation exchange capacity, rheological properties, catalysis and other physical and chemical properties. Meanwhile, the treatment of acid, heat, salt exchange, purification and organic modification can effect and significantly improve the physicochemical properties of attapulgite clay. Among them, the acid changes its charged, adsorption, cation exchange capacity and specific surface area; With the rise of temperature, heat makes its surface area increasing to a maximum and then declined sharply; Purification improves colloid performance; Organic modification makes the particle surface of clay translate from full hydropho-bic to part hydrophilic, changes the specific surface area and cation exchange capacity, enhances the performance of colloidal suspension.关键词
