【 摘 要 】

References(6)Cited-By(1)The purpose of this study is to create a dehalogenation material made of wood powder cheaply. The dehalogenation material consists of an inorganic and organic compound. The sodium was adsorbed to the surface of the wood powder by ionic-bonding using low-temperature plasma irradiation. For the wood powder material, unwanted lumber from thinning trees in forests and scrap wood could effectively be utilized. This dehalogenation material, which consists of wood powder and sodium, can easily be used for an environmental cleanup business, because this material is biodegradable. When the sodium wood powder was put in water, highly-dense sodium ion concentration of 80 mg/L was released. The sodium wood powder was left in a hydrogen chloride gas atmosphere to examine the dehalogenation characteristics. As a result, it was verified that the chlorine was able to be removed from the hydrogen chloride. The sodium wood powder created in this experiment can be utilized as an adsorption material for contaminated soil with dioxins and PCB, also from vehicle emissions and for hydrogen chloride gas that would have been rejected by incineration facilities.
