    • An object is to provide a method for producing an aqueous hydrogen peroxide solution, which can effectively remove an impurity, such as silicic acid or a silicate, contained in an aqueous hydrogen peroxide solution. The method of the present invention for producing an aqueous hydrogen peroxide solution has a first step for contacting an aqueous hydrogen peroxide solution with activated alumina which has been cleaned with purified water, and a second step for, after the first step, contacting the resultant aqueous hydrogen peroxide solution with a cation-exchange resin. The cation-exchange resin is preferably a hydrogen ion-type, strongly acid cation-exchange resin having a sulfonic acid group. The aqueous hydrogen peroxide solution being in contact with the activated alumina and the cation-exchange resin preferably has a temperature of 30° C. or lower.
    • 目的是提供一种生产过氧化氢水溶液的方法,其可以有效地除去过氧化氢水溶液中所含的杂质如硅酸或硅酸盐。 本发明的用于生产过氧化氢水溶液的方法具有使过氧化氢水溶液与用净化水清洗的活性氧化铝接触的第一步骤,第二步是在第一步骤之后,使所得水溶液 过氧化氢溶液与阳离子交换树脂。 阳离子交换树脂优选为具有磺酸基的氢离子型强酸阳离子交换树脂。 与活性氧化铝和阳离子交换树脂接触的过氧化氢水溶液的温度优选为30℃以下。
