| 摘要 |
The present invention provides a method for continuous production of ultra-pure aqueous hydrogen peroxide solution. Industrial grade aqueous hydrogen peroxide solution as raw material is pretreated by macroporous adsorption resin, and then is brought into contact with a cation exchange resin, anion exchange resin to the first ion exchange. Then the material is brought into contact with multi-stage mixed cation and anion exchange resin columns, and is filtered by ultrafilter to obtain ultra-pure aqueous hydrogen peroxide solution. The method provided by the present invention has high security, simple operation, stable quality of product, and is suitable for continuously produce on a large scale. |
