摘要： Provided is a process for the preparation of an ultrapure hydrogen peroxide solution. The process comprises at least one sequence which includes passing a solution to be purified successively through at least one bed of anion-exchange adsorbents (AEA) and at least one bed of cation-exchange adsorbents (CEA). A non-zero proportion of the solution exiting from one of the beds is recycled to a point upstream of the one bed or upstream of a preceding bed or upstream of the first bed of the first of the at least one sequence. Also provided is a plant for the implementation of the inventive process.

摘要： A method using auto-oxidation of an anthraquinone derivative in three successive steps, comprising hydrogenating the working solution (at 1), oxidizing the hydrogenated working solution (at 2), and removing hydrogen peroxide using water (at 3). The hydrogenation step is performed in such a way that a hydrogen peroxide equivalent of around 7.9 g/l is achieved at the inlet of the oxidizer (2), and the oxidation step (b) is performed in such a way that the temperature at the top of the oxidizer (2) is below about 50.degree. C., and preferably around 35-40.degree. C. The method is useful for producing hydrogen peroxide in situ in a paper pulp bleaching plant.
