The conversion of ferrous sulphate to ferric sulphate is

Effective date : Year of fee payment : 4. Year of fee payment : 8. Year of fee payment : A process is provided for preparing a preferred ferric sulfate solution. The product of the process is particularly suited for use in water treatment and purification. According to the process, iron oxides or iron, are dissolved in sulfuric acid to form ferrous sulfate. In a first step of oxidation, the ferrous sulfate is partially oxidized to ferric sulfate in the presence of dissolved oxygen. In a second stage of oxidation, remaining ferrous sulfate is oxidized to ferric sulfate by the action of a non-molecular oxygen oxidizing agent such as hydrogen peroxide. During both stages of oxidation, a catalyst such as copper sulfate or copper ammonium sulfate may be used. Careful control of added sulfuric acid is maintained, to avoid excess or free sulfuric acid in the reaction product. In this specification, iron III sulfate refers to an iron salt with the iron in the ferric form, and iron II sulfate refers to an iron salt with the iron in the ferrous form or ferrous oxidation state. It is well known that various hydroxides may be used as coagulating or floc producing agents in water purification and treatment facilities. The floc formed from such agents may be used to trap undissolved materials in the water such as organics, inorganic precipitates, and various biological matters. The floc precipitate generally effectively attracts and absorbs even very fine contaminating particles.

A coordination entity formed when excess of aqueous KCN is added to an aqueous solution of copper sulphate? It has been found that temperature ranges outside of the preferred range may result in the precipitation of products such as iron oxide or the precipitation of some starting material ferrous sulfate, from the solution. It is foreseen that a mixture of iron II oxides and iron III oxides may be converted to the preferred iron III sulfate solution, according to the present invention, as follows:. Ceric ammonium sulphate and potassium permanganate are used as oxidisi Was this answer helpful? The crystals of ferrous sulphate on heating give :. A process in which a metal or its ion loses one more electrons is called an oxidation. A process for the preparation of a ferric sulfate solution by the oxidation of ferrous sulfate in the presence of sulfuric acid; said process including the steps of: a providing an aqueous solution having ferrous sulfate dissolved therein as an initial reaction solution;. When electric current is passed through acidulated water of electrolysis water takes place. The ration of number of moles of stannous sulphate required per mole of ferrous ammonium sulphate to the number of moles of K M n O 4 required per mole of ferrous ammonium sulphate, is:. USB2 en. Oxidation, displacement, electrolysis, reduction, zinc, copper, double displacement, decomposition a. Generally, these can be traced to problems arising during the initial ferric sulfate production, and in the composition of the ferric sulfate agent used, rather than any inherent problem in the use of ferric sulfate itself.

It will be readily understood that the length of time required to dissolve the iron will vary, in part depending upon the particle size of the iron scraps used. A process according to claim 5 wherein:. That is, if complete oxidation were achieved, the solution would contain ferric sulfate with substantially no excess or free sulfuric acid present.
