Abstract

Physicochemical properties and copper (II) adsorption ability of two oakwood and two pinewood charcoals, which were manufactured in traditional mode and commercialized in Korea, were examined pHs of these four wood charcoals were between 9.5 and 9.8. In the elemental contents of the wood charcoal, the contents of carbon atom (C) in the four samples were between 85-90%, while the content of hydrogen atom (H) in pinewood charcoal of the company 'S' was 1.62% and this value was three time higher than those of other samples. For iodine adsorption and specific surface area, the pinewood charcoal sample showed higher values than those of the oakwood charcoals. In the copper (II) ion adsorption in aqueous solution, the adsorption rate was increased by the increase of treated amounts of charcoal, treatment time, and pH.
