Study on ferrous sulfate microencapsulation;

Preparation of nanometer ferric oxide from ferrous sulfate by liquid phase method;

Preparation of highpurity manganese dioxide by leaching manganese ore with ferrous sulfate from by-product of titanium white;

The ferrous sulphate is obtained in the way that pyrite cinder is first deoxidized via roasting;then leached with acid,treated through pH value adjustment,provided with flocculant and finally settled.

This article has reported the existing of secondary seed-real seed during synthesis of ammonium neutralized iron oxide by use of ferrous sulphate and described the forming process of real seed in the early stage of oxidation(two-step oxidation).

In order to treat the wastewater from vat blue production,we obtain ferrous sulphate as water treatment chemical and incinerate residue in general coal-fired boiler.

Influence of FeSO_4 on the Growth and Development of Edible Fungi Hypha;

NEGATIVE INOTROPISM OF THE EFFECT OF FeSO_4 ON ISOLATED GUINEA PIG HEART ATRIUM;

The polymerization of styrene was living when the molar ratio of AIBN/NaNO_2/FeSO_4·7H_2O was 1/2.

Research on Testing of Producing Sulphuric Acid by Roasting Sulfurous Iron Ore with Ferrisulphas;

The aim of the paper was to study the inactivation of soybean trypsin inhibitor by ferrisulphas.

By introducing the chemical and absorbing treatment with ferrisulphas and aluminum sulfate before the traditional treating method, the result can meet the national effluent standard and no repollution occurs.

The concentration of FeSO 4 was determined by micro titration with a novelly designed pipette and KMnO 4 standard solution.

The result shows that it is effective to use the waste liquor containing FeSO 4 as flocculant.

There is a vice-product FeSO4 in the process.

FeSO4 is used as coagulation agent in pretreatment process,the activated sludge process and biological contact oxidation process are jointly applied in the aerobic treatment stage.
