Title:
効果的なダイオキシン類の除去方法
Document Type and Number:
Japanese Patent JP4172907
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and apparatus capable of relatively safely and inexpensively decomposing dioxins in gas, soil or the like containing a very small amount of dioxins to remove them. SOLUTION: Mixing action is applied to gas or fluid containing dioxins having at least two cyclic structures in one moleucle thereof or matter to which dioxins adhere so as to bring a metal phthalocyanine derivative and an oxygen supplying compound such as hydrogen peroxide or the like into contact with the gas or fluid at the same time to effectively remove dioxins. Dioxins can be effectively decomposed at a low temperature by a wet system without relying on an expensive method such as an ultrahigh temperature treatment method or the like. A method for safely treating the metal phthalocyanine derivative accompanied by this dioxin removing method can be provided. This dioxin removing method and apparatus can reply to an emergent and important social demand and can prevent environmental disruption and can be widely and practically applied to industry. Safe standards of dioxins can be lowered to more safe standards.
