The Preparation of Inorganic Coagulant-Poly Ferric Sulfate
The oxidation of ferrous sulfate with oxygen under the catalysis of nitrogen oxides is controlled by the adsorption of nitrogen oxides in gas phase. The detailed reaction mechanism was proposed and confirmed by the experiment. A rational technology was designed and put into use.
