BACKGROUND:The number of biomass power plants is increasing around the world and amount wastes from expected to increase.But bottom ash (BA) not recycled has been dumped in landfill.This study was conducted find out functional groups BA adsorption rate heavy metals on BA. METHODS AND RESULTS:The dried oven at 105℃ for 24 hours, characterized by analyzing chemistry, group, surface area.The rates were evaluated different concentration, time, pH.As a result, high order Zn> Cu> Cd> Ni removal Zn, Cu, Cd, 49.75, 30.20, 32.46, 36.10%,respectively.Also, maximum capacity metal environmental conditions, it suggested that isotherms Ni, Cu adequate Langmuir model. CONCLUSION(S):It would be effective remove aqueous solution using South Korea.
