【Abstract】 Attapulgite is an industrial mineral with the advantages of non-toxicity,large surface area and biocompatibility. It can be effectively used in traditional industries and also has potential applications in high and new technology. In this paper,the basic characteristics of attapulgite,including its composition,distribution and crystal structure are described. The research progress of attapulgite used alone or blended in inorganic-organic composites,adsorption,papermaking,electrochemistry and catalysis are reviewed. Especially,the latest applications of attapulgite as biosensors,photo- and electro-catalysts are mentioned. The advantages and existing problems of attapulgite are also summarized.The development of functional attapulgite-based products of high quality and high additional value is necessary for effective utilization of attapulgite resource.更多还原
