A green method for ceric hydroxide synthesis with cerium carbonate and hydrogen peroxide as main raw materials is reported, and two products, ceric hydroxide and sodium acetate, are obtained. The effects of feeding procedure of hydrogen peroxide, the amount of hydrogen peroxide added, reaction temperature, cerium acetate concentration and sodium hydroxide added on the oxidation of cerium are investigated. Ceric hydroxide is characterized by a scanning electron microscope. The oxidation percentage of cerium is over 98%, and the recovery over 99%.
