Ferrate(VI): A Green Chemistry Oxidant for Removal of Antibiotics in Water

Popis výsledku v původním jazyce

Ferrate(VI) ((FeO42-)-O-VI, Fe(VI)) ion is an environmentally-friendly chemical for water treatment, which can peform a dual function of oxidation and disinfection and forms a non-toxic byproduct, iron(III). This chapter presents an assessment of the potential of ferrate(VI) to oxidize antibiotics (A). The kinetics, stoichiometry, and products and their antibacterial properties are presented. The second-order rate constants, k, of the oxidation reactions at neutral pH were in the range from 5.0 x 10(-1)- 1.5 x 10(3) M(-1)s(-1). At a 10 mg L-1 K2FeO4 dose, half-lives of the oxidation reaction would be in seconds to minutes at a neutral pH. The values of k, and the reaction half-lives, varied with pH. The stoichiometry of the reactions of Fe(VI) with sulfamethoxazole and trimethoprim were 4:1 and 5:1 ([Fe(VI): [A], respectively. Oxidation products of the reactions were found to be relatively less toxic than parent molecule. The oxidized products of trimethoprim showed no significant ant
