The mechanism of Fe³⁺catalyzed oxidation of S(IV) is the combination of catalyzed oxidation and radical reaction, the O₂^- produced from the oxygen in solution plays a very important role for the oxidation of S(IV),which determines the mode and process of the reaction. In the absence of catalyst, the oxidation of S(IV) is relatively slow in the liquid, the reaction rate depends on the concentration of dissolved oxygen. When pH is 2.80, the reaction rate constant of Fe³⁺ catalyzed oxidation of S(IV) is 588 (mol / L)^-1 · s^-1.). The study results confirmed that Fe³⁺ has a strong oxidation effect on S(IV). By maintaining the concentration of Fe³⁺ and dissolved oxygen in the liquid, we can get a stable desulphurization efficiency.
