Abstract
Hydrogen peroxide solutions are purified by producing therein a precipitate of stannic hydroxide by the addition of a colloidal sol of stannic hydroxide, the hydrogen peroxide solution being acid, e.g. having a pH between 1,4 and 3,5, at the time of precipitation. The resulting precipitate may be either removed by filtration or decantation or left in contact with the solution. The stannic hydroxide sol may be prepared by precipitating a gel by the addition of sulphuric acid to a sodium stannate solution, filtering the gel, washing it with water and peptizing it in water with the aid of ammonia. Alternatively, alkali metal hydroxide may be used as the peptizing agent. A stabilizer may be added to the purified solution. Reference has been directed by the Comptroller to Specifications 409,361 and 432,915.
