Hydrogen peroxide recovery from colored aqueous solutions |
摘要 |
A method of recovering hydrogen peroxide from colored aqueous solutions is disclosed. The solution is brought in contact with a non-ionic size-exclusion chromatography resin made up of packed particles having narrow, low molecular weight pores. The higher molecular weight colored constituents are largely excluded from the pores causing these constituents to be more rapidly eluted with water along the exterior of the particles. Hydrogen peroxide molecules are small enough to enter the pores several times in their passage through the resin which slows their progress sufficiently to cause elution of hydrogen peroxide after the colored constituents have been eluted, effectively resolving the two components.
