The invention provides a method for preparing vanadyl sulfate. According to the method, a technical process that ion exchange resin is adopted to selectively adsorb vanadium and reduce and desorb vanadium so as to directly prepare vanadyl sulfate is adopted, so that a middle process in which powder high-purity vanadium pentoxide is prepared is canceled. In addition, as the decontamination process is evolved into direct selective pure vanadium extraction, contamination and the labor and material consumption in the decontamination process are avoided, the operation procedure is greatly simplified. Compared with a conventional vanadyl sulfate preparation process, the method has the advantages of short procedure, high vanadium yield, low cost, no waste discharge and the like.
