摘要： A process for purifying a hydrogen peroxide solution is disclosed, comprising treating a 10 to 60% by weight hydrogen peroxide solution having a pH between 1.5 and 5.0 and containing anionic impurities with a hydrogencarbonate type or carbonate type anion exchange resin while adding an acid or a salt thereof having an acid dissociation constant pKa in water of not more than 5 to the hydrogen peroxide solution to be treated continuously or semi-continuously in an amount of from 0.5 to 5 milli-equivalents per liter of hydrogen peroxide solution. The hydrogen peroxide decomposing activity of the anion exchange resin can be inhibited without decreasing a rate of removal of strong acid radicals in the anionic impurities thereby minimizing oxygen evolution due to decomposition of hydrogen peroxide.
摘要翻译：公开了一种用于纯化过氧化氢溶液的方法，其包括在加入酸或酸的情况下，将pH为1.5-5.0的10至60重量％的过氧化氢溶液和含有阴离子杂质的碳酸氢盐型或碳酸盐型阴离子交换树脂其在水中的酸解离常数pKa为不超过5的连续或半连续的过氧化氢溶液，其量为0.5-5毫当量/升过氧化氢溶液。可以抑制阴离子交换树脂的过氧化氢分解活性，而不会降低阴离子杂质中强酸性基团的除去速率，从而最小化由于过氧化氢分解引起的氧析出。
