磷酸活化稻秆制备中孔活性炭的研究
Preparation of Mesoporous Activated Carbon from Rice Straw Using Phosphoric Acid
摘要
Abstract
Mesoperous activated carbon was prepared from rice straw by chemical activation with phosphoric acid and characterized by N2 adsorption,elemental analysis and scanning electron micrograph.The results showed that activated carbon was pre-ac-tivated at 140 ℃ for about 60 min and then prepared at the impregnated ratio 3:1 (mass ratio),activation temperature 450 ℃,activation duration 60 min.Under this condition,characteristics of activated carbon are:the yeild 25％,methylene blue adsorption value 215 mg/g,iodine adsorption values 835 mg/g,decolorization of caramel (A) 110％,ash content 3.03％,pecific surface area 967.7 m2/g,total volume 1.12 cm3/g,average pore diameter 4.6 rim.The ration of mesopores of activated carbon made from rice straw is 84.8 ％.Rice straw can be used as the material to prepare activated carbon with mesoperes.关键词
