The Properties of Activated Carbon Made from Waste Newsprint Paper

Activated carbon is a porous material made by activation of carbon materials, such as coal, by steam or carbon dioxide 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 develop a new use for waste paper, activated carbon was prepared from waste newsprint paper and its adsorption characteristics were measured. As a result, activated carbon with an iodine adsorption capacity of 1310 mg/g, a methylene blue adsorption capacity of 326 mg/g and a specific surface area of 1000 m2/g was obtained. These adsorption capacities were almost the same as ordinary activated carbon on the market.
