Abstract
The effective utilization of the bamboo which was unused organic resources was considered, and heavy metal adsorption ability of the bamboo carbide was compared with it of wooden charcoal and activated carbon. As the result, pH of the bamboo charcoal showed the basicity regardless of the carbonization temperature, and it became clear to have the adsorption ability which bamboo charcoal which mainly contains the potassium is excellent. Then, the practically experiment was carried out on heavy metal adsorption ability in the street dust in utilizing the bamboo charcoal under the planting tree in the roadside as a mulching material. It became clear to be effective in the control of the heavy metal pollution by laying the bamboo charcoal under the planting.
