Activated carbon is a porous material made by activation of carbon material
s, such as coal, by steam or carbon dioxide gas to form numerous micropores
on the surface which gives the material high adsorption characteristics an
d it is widely used as a purifier for water and air. In this research, to d
evelop a new use for waste paper, activated carbon was prepared from waste
newsprint paper and its adsorption characteristics were measured. As a resu
lt, activated carbon with an iodine adsorption capacity of 1310 mg/g, a met
hylene blue adsorption capacity of 326 mg/g and a specific surface area of
1000 m(2)/g was obtained. These adsorption capacities were almost the same
as ordinary activated carbon on the market.
