| 摘 要： | 在KIO_3-HCl体系中,用氮分子激光作激发光源,研究了铈的价态变化。三价铈的碘酸盐能溶于酸性永溶液,而在激光辐照后,却均匀地、逐渐地生成黄色沉淀。经红外光谱及化学分析证明,此沉淀为四价铈的碘酸盐。

Study on valency change of cerium by laser |
| |
| 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. |
