CATALYST FOR INDUCING THERMAL DESORPTION OF ORGANIC MATTER-CONTAMINATED SOIL AND PREPARATION METHOD THEREOF
A catalyst for inducing thermal desorption of organic matter-contaminated soil and a preparation method thereof, which uses a colloidal mixture of ferroferric oxide and ferric chloride as a catalytic active component of thermal desorption, and carbon tetrachloride as a solvent. Based on the mass of solvent, a mass percentage of catalytic active component is 0.1%-15%. Ammonia water is added dropwise to ferric chloride aqueous solution to react in oil bath to generate a ferroferric oxide colloidal solution, then ferric chloride and obtained ferroferric oxide colloidal solution are added to carbon tetrachloride, and mixed solution is continuously stirred in an oil bath to evaporate solvent water to prepare a catalyst with carbon tetrachloride as solvent. Catalyst is environmentally friendly and can induce thermal desorption of organic matters in soil. 100% desorption of chlorobenzene, o-xylene and benzo[A]anthracene can be achieved at 130° C., and energy consumption of thermal desorption is greatly reduced.
