Abstract: | The oxidation rate of ferrous sulfate was investigated in the preparation of polyferric sulfate(PFS) coagulant. It was proved that this reaction is zero order with respect to Fe 2+ , first order with respect to NO\-2(g) and first order with respect to the interface area between gas phase and liquid phase. If the partial pressure of NO\-2(g) in gas phase is increased or the interface area is increased, the time needed to complete the reaction will be decreased. |
