The oxidation of iron(II) sulfate with SO2/O2(sulfur dioxide and oxygen mixtures) was carried out using an air-lift percolator in the temperature range of 25–50 °C and over the pH range of 0–3. Under conditions in which sulfur dioxide is immediately oxidized, the rate of the oxidation of iron(II) is proportional to the flow rate of sulfur dioxide and independent of the flow rate and partial pressure of oxygen, and the concentration of iron(II). The molar ratio of Fe2+oxidized/SO2oxidized is 1.3–2 in the pH range of 0.5–2.0. A free-radical chain reaction in which HSO5-oxidizes iron(II) is proposed as the reaction mechanism. |
