Japanese cedar (Cryptomeria japonica D. Don) wood powder carbonized at varying temperatures was used to remove mercury from aqueous solutions of different types of mercury compounds. Aqueous solutions of different types of mercury compounds were prepared at 5 ppm to determine the amounts of mercury removed by these materials. In all cases, wood powder carbonized at 1000°C performed best among the carbonized wood materials examined, even better than activated carbon. Mercury was removed even when ovendried wood powder and wood powder carbonized at 200°C were used. The ability of wood powder carbonized at 600°C to remove mercury was also promising.
