In this study, thermal decomposition of Hinoki chips soaked in Ca solution and adsorption properties of obtained charcoal for nitrate nitrogen were investigated to develop a novel functional charcoal. Ca(OH)<SUB>2</SUB> was used as Ca source due to less environmental load and easy handling and Ca-impregnated chips were heat-treated in an electric muffle furnace at temperatures between 600 and 900°C. The Ca-loaded charcoal acid-treated with HCl exhibited adsorptive ability for nitrate nitrogen. It was revealed that adsorption of nitrate nitrogen was ion-exchange reaction and that the charcoal samples acid-treated with HCl could be regenerated repeatedly by exchanging nitrate ion for chloride ion. The measurements of adsorption properties for nitrate nitrogen revealed that the adsorptive ability and durability of these samples were higher than those of activate carbon and anion-exchange resin. It was also found the obtained charcoal exhibited selective adsorption for nitrate nitrogen and fluoride anion, but not for sulfuric acid and phosphoric acid anions. As the result, the simple method, Ca-impregnation, thermal decomposition and acid treatment of wood waste, has advantages in production of nitrate nitrogen adsorption material.
