Abstract: The present invention is a method of stabilizing hydrogen peroxide in an aqueous solution, such as a circulating water slurry, comprising a peroxide, such as hydrogen peroxide. The aqueous solution may include organic matter. The method comprises adding an aldehyde donor, such as a methylolhydantoin, to the solution (or slurry). The inventors have discovered that aldehyde donors significantly reduce the decomposition of hydrogen peroxide by catalase and other peroxide decomposing enzymes, which are often present in recycled paper. As a result, less hydrogen peroxide needs to be added to a solution to effectively bleach organic matter in the solution. Furthermore, aldehyde donors are safe to handle and cost effective. Another embodiment is a method of bleaching recycled papers in a circulating water slurry comprising organic matter. The method comprises adding hydrogen peroxide and an aldehyde donor to the slurry. Yet another embodiment is a method of inhibiting catalase and/or other peroxide decomposing enzymes in an aqueous solution, such as a circulating water slurry, comprising adding an aldehyde donor to the aqueous solution.

Abstract translation: 本发明是一种在过氧化氢如过氧化氢等水溶液例如循环水淤浆中稳定过氧化氢的方法。 水溶液可以包括有机物质。 该方法包括向溶液（或浆液）中加入醛供体，例如羟甲基乙内酰脲。 发明人已经发现，醛供体通过过氧化氢酶和其它过氧化物分解酶显着降低过氧化氢的分解，这些酶通常存在于再生纸中。 因此，需要将较少的过氧化氢加入到溶液中以有效地漂白溶液中的有机物质。 此外，醛供体可以安全处理和具有成本效益。 另一个实施方案是在包含有机物质的循环水浆液中漂白再循环纸的方法。 该方法包括向浆液中加入过氧化氢和醛供体。 另一个实施方案是在水溶液如循环水浆液中抑制过氧化氢酶和/或其它过氧化物分解酶的方法，包括向所述水溶液中加入醛供体。
