Progress on the preparation of ultra-pure hydrogen peroxide is reviewed. The technologies include distillation and relative technologies, combination methods of ion exchange and adsorption resin, membrane separation and relative technologies, crystallization, flocculation, and adding addition agents as so well. Distillation is reliable and easy to industrialize, while purity of hydrogen peroxide distilled is not high enough. Crystallization, flocculation, and adding addition agents can only be used as accessory technologies. It is safe for membrane separation, but the life of membrane is short. Ion exchange and adsorption resin processes are simple and the product purity is high, but ion exchange resin is easy to be oxidized. It is the tendency for the preparation of ultra-pure hydrogen peroxide that distillation is used firstly and then the combination of membrane separation technologies or ion exchange and adsorption resin processes are followed.
