The wasted catalyst, the water, and the ammonia air mixed in the weight ratio of 1:0.6-3:0.1-2 and are tumbled at the speed of 15-100rpm. The property of the catalyst separates water solution and the supporter, and the separated catalyst supporter is washed, dipped in the separated water solution, heated at the temperature of 50-80 degree C. At this time, the solution is stirred up, the water solution and the supporter are tumbled as it is heated, the supporter and the water solution are separated, the supporter is washed in the water, or after washing, dipped in a nitric acid or acetic acid water solution, washed in the water and is dried up to collect a oxidation catalyst supporter.
