摘　　要：In this study the aqueous oxidation kinetics of estriol(E3)by potassium ferrate(K_(2)FeO_(4)),a chemical for its strong oxidizing power and for producing a coagulant from its reduced state(i.e.Fe(III)),was evaluated in the range of pH 8–12 with different molar ratios of the reactants.As the degree of Fe(VI)protonation varies with the solution pH,it was found that afirst order model was not suitable to describe the oxidation reaction.This paper describes a theoretical representation that closely models the reaction kinetics of E3 and ferrate.From this modeling,the reaction rates of HFeO_(4)^(-) and FeO_(4)^(2-) with E3 have been determined.The results show that the reactivity of HFeO–with dissociated and undissociated E3 is greater than that4 of FeO_(4)^(2-),and that E3 is more reactive in its dissociated state.
