    Abstract

    The valency change cf cerium induced by using nitrogen laser for excitation of KIO3-HCl system has been studied. Cerous iodate is soluble in acidic aqueous solution, but a yellow precipitate is formed homogeneously and gradually after irradiation by laser. It is proved by IR spectrum and chemical analysis that this precipitate is eerie iodate.
