Abstract
The present invention is a new, easy method for preparing stable solid Fe6+—Fe3+ agents in a fixed bed reactor by using O3 and FeOOH along with KOH with conversion efficiencies of approximately 27%. In addition, the product has been used to oxidize oil from water and to destroy tetracycline in water
Claims16
A method of making solid Fe(VI), comprising the steps of:
- (a) adsorbing an alkali metal hydroxide onto Fe(III) oxide-hydroxide to produce a Fe(III) composition;
- and
- (b) exposing the Fe(III) composition to ozone to convert the Fe(III) to Fe(IV).
A method of making solid K2FeO4, comprising the steps of:
- (a) adding a source of FeOOH to an aqueous solution of potassium hydroxide to form a reaction mixture;
- (b) drying the reaction mixture to form a dry Fe(III) composition;
- (c) adding the Fe(III) composition mixture to a reactor;
- and
- (d) passing ozone over the Fe(III) composition in the reactor to convert the Fe(III) to Fe(IV).
