| titleOfInvention | Preparation method of amorphous iron sulfide catalyst for heterogeneous Fenton oxidation reaction |
| abstract | The present invention relates to a method for preparing an amorphous iron sulfide catalyst for heterogeneous Fenton oxidation reaction that effectively removes hardly decomposable organic materials by stabilizing iron hydroxide broken by hydrogen sulfide in an inert atmosphere. The present invention provides an iron hydroxide preparation step for adsorption of hydrogen sulfide (S10) of preparing iron hydroxide having pores and surfaces capable of adsorbing hydrogen sulfide; generating an amorphous iron sulfide for generating amorphous iron sulfide by introducing hydrogen sulfide into the prepared iron hydroxide to break through the iron hydroxide (S20); an oxygen blocking step (S30) of supplying amorphous iron sulfide produced by reaction with hydrogen sulfide to a heat treatment apparatus and introducing an inert gas to remove oxygen; and a heat treatment step (S40) of heat-treating amorphous iron sulfide by heating a heat treatment apparatus in an inert gas atmosphere from which oxygen has been removed with an inert gas at about 100 to 800°C. |
