Vanadium sulfate preparation method

The invention discloses a vanadium sulfate preparation method which comprises redox reaction of vanadyl sulfate and acetone in the presence of concentrated sulfuric acid. The vanadium sulfate preparation method has the characteristics of simple operation and short reaction period, due to the reduction of electric energy consumption and no use of zinc powder, the production cost is reduced. In addition, vanadium sulfate prepared by the method can exist in a solid form, and the cost of transportation is saved.
