More Information
Summary:PURPOSE: A purifying method of the hydrogen peroxide liquid containing impurities is provided to eliminate some of anion impurities at least by passing through one or more first resin of the anion type, and then by passing through a second resin of the cation type to remove some of cation impurities, or by reversing the order. CONSTITUTION: A purifying method of the hydrogen peroxide liquid containing impurities comprises of follows: parallel arrangement of a first and a second layers in the first resin of the anion type; making alternative influx of the above liquid into the above first or the second layer; and performing a turnover from the first to the second layer (or the reverse way) when the resin contained in the first layer partially exchanges an ion at least with more than one anion comprising anion impurities.
