Abstract: 
The oxidation rate of ferrum(II) to ferrum(III) by air oxygen in water has been investigated in the horizontal absorber with bucket-like dispersers. The reaction order relative to Fe2+ and –OH ions has been determined based on established dependencies of ferrum(II) ions concentration on dispersion time at their various initial concentrations and medium pH. It has been shown for the first time that at pH = 5.5–6.2 in water during oxidation of ferrum(II) ions an autocatalysis occurs due to the formed ferrum(III) ions.
