M.Shimada,K.Kawarada,T.lida,T.Okayama 한국펄프·종이공학회 1999 한국펄프종이학회 기타 간행물 Vol.- No.-
Activated carbon is a porous material made by activation of carbon materials, such as coal, by steam or carbon diaxide gas to form numerous micropores on the surface which gives the material high adsorption characteristics and it is widely used as a purifier for water and air. In this research, to developanew use for waste paper, activated carbon was prepared from waste newspaper and its adsorption characteristics were measured. As a result,activated carbon with an iodine adsorption capacity of 810 mg/g, a methylene blue adsorption capacity of 220 mg/g and a specific surface area of 1000㎡/g was obtained. These adsorption capacities were almost the same as ordinary activated carbon on the market.
