Hematite Precipitation from High Iron Solution in
2018年1月19日 The reactions represented by Eqs. 3 and 4 occur at different places in the bulk solution: the oxygen concentration in the solution is determined by the rate of ferrous oxidation while the oxygen concentration at the gas–liquid interface depends on oxygen mass transfer rate. Consequently, the oxygen concentration in the solution may differ from that at the gas–liquid
