platinum sulfate is an important metal sulfate compound used in applications such as water treatment, petrochemical cracking and automotive catalysts. It is also commonly used in plating, textiles and research as an elemental standard.

American Elements produces moderate to highly concentrated liquid solutions of platinum sulfate at a wide range of concentrations and stoichiometric ratios for a variety of uses. The solutions are produced in our own laboratories at a production facility in the United States and shipped to customers worldwide via a number of distribution channels.

A moderate to high concentrated solution of platinum sulfate can be produced by reacting a soluble salt of the metal with sulfuric acid in a solvent, such as water or alcohol. The resulting solution is usually dissolved in a capillary or spray dryer and cooled to room temperature before use.

Another method for preparing a sulfate solution of platinum is the dissolution of potassium chloroplatinite and ammonium acetate in water. The cis-dichlorodiamminoplatinum (II) is generated through a reaction with the ammonium acetate to form tetraammineplatinum chloride (II). After the tetraammineplatinum is dissolved in a solution of sulfuric acid, the chlorine ions are removed by backflow.

In the embodiment of the present invention, 1000g potassium chloroplatinite and 450g ammonium acetate are mixed in a volume of 50L of water with vinegar acid for adjusting pH value to 5. The tetraammineplatinum sulfate is then added and the reaction is refluxed for 5h. After the solution is decompressed, it is filtered and the solid is separated out.
