Ammonia reacts with nickel sulfate to ..

The above methods allow to obtain the pure target product with satisfactory output. Their disadvantage is the need for the extra cost of the reagent - sulfate Nickel(II).

Nickel Ammonium Sulfate | Spectrum

14. The method according to claim 1, characterized in that for the preparation of the reaction of an aqueous solution containing Nickel(II)ammonium sulfate as a source of sulfate uses sulfuric acid and/or ammonium sulfate.


Ammonium nickel(II) sulfate hexahydrate - 100G , …

The method of producing uranyl sulfate Nickel-ammonium based on the chemical reactions, for example:

This method allows you to obtain the target product and return it to the cycle of production of Nickel powder, however, it requires additional costs for reagent - sulfate Nickel(II) and does not use to obtain the target product waste solutions chemical Nickel plating.


T3DB: Nickel ammonium sulfate hexahydrate

The invention relates to chemical technology of inorganic substances, in particular to a method for producing uranyl sulfate Nickel-ammonium (NH4)2Ni(SO4)2·6H2O. the Claimed method can be used for the extraction of Nickel(II) from toxic waste - waste solutions chemical Nickel plating. The substance obtained in this way can be used to prepare electrolyte galvanic Nickel plating, to obtain single crystals with valuable physical properties, for various Nickel compounds.

Nickel ammonium sulfate is a chemical ..

A method of obtaining large single crystals of uranyl sulfate Nickel-ammonium from aqueous solution containing Nickel sulfate(II) and ammonium sulfate (Sobolev L.V., Kirpichnikova L. F. // crystallography, 2001, Vol.46, No. 2, S).

15699-18-0 | NICKEL AMMONIUM SULFATE | …

A known method of producing uranyl sulfate Nickel-ammonium from aqueous solution obtained by mixing a warm saturated solution of Nickel sulfate(II) and ammonium sulphate, taken in a molar ratio of 1.0:1.0, followed by evaporation of the reaction solution until a crystalline precipitate (NH4)2Ni(SO4)2·6H2O (Klyuchnikov N.G. Guide inorganic synthesis. - M.: Chemistry, 1965, S). The disadvantage of this method is the need for the extra cost of heat is the W solution and reagent sulfate Nickel(II).

AMMONIUM NICKEL(II) SULFATE HEXAHYDRATE 98% …

The task of resets the same time, the method of producing uranyl sulfate Nickel-ammonium involves cooking the reaction of an aqueous solution containing Nickel(II), ammonium and sulfate, the crystallization of the desired product, separating the crystals from the solution. New this method is that for the preparation of the reaction of an aqueous solution as the source of Nickel(II) use production waste is the spent chemical Nickel-plating solution, thus prepared reaction aqueous solution with a mass fraction of ammonium from 3 to 15% and the mass fractions of sulfate from 8 to 45%, and the crystallization of the desired product from the solution is carried out at a temperature of from -5 to 40°C. To obtain uranyl sulfate Nickel-ammonium desirable to use the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hypophosphite sodium, postit sodium, acetic acid, sodium acetate, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hypophosphite sodium, postit sodium, acetic acid, ammonium sulfate, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hypophosphite sodium, postit sodium, dairy or aminouksusnoy acid, sodium acetate, or exhaust the chemical solution nickeliron what I which as a main component contains Nickel(II), hypophosphite sodium, postit sodium, sodium citrate, ammonium chloride, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hypophosphite sodium, postit sodium, ammonium chloride, ammonia, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hypophosphite sodium, postit sodium, hydroxyethylidenediphosphonic sodium, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), borohydride sodium, sodium borate, the Ethylenediamine, sodium hydroxide, sodium carbonate, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), dimethylaminoborane, boric acid, ammonium succinate, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hydroxymethanesulfinic sodium, hydroxymethanesulfinic sodium, sodium sulfite, sodium sulfate, ammonia, or the spent chemical Nickel-plating solution, which is the main component contains Nickel(II), hydrazine, ammonia, ammonium sulfate. To prepare the reaction of an aqueous solution as the source of ammonium is desirable to use the ammonia and/or ammonium sulfate, and as a source of sulfate - sulfuric acid and/or ammonium sulfate. It is desirable to prepare the reaction aqueous solution with a pH from 0.5 to 8.0.
