| 摘 要： | 用Ｘ射线光电子能谱（ＸＰＳ）和气相色谱（ＧＣ）分析研究了ＣＯ对金属铀表面氧化层的影响。ＣＯ在表面氧化层上的吸附反应导致了Ｕ４ｆ峰向低结合能方向位移，氧化物中氧含量减少，原子比（Ｏ／Ｕ）比值下降了７．２％。体系中ＣＯ２体积分数增大１１．０％。研究结果表明，ＣＯ气氛可抑制金属铀表面的进一步氧化。

| Abstract: | The influence of carbon monoxide to the surface oxide layer of uranium metal has been studied by X ray photoelectron spectroscopy(XPS) and gas chromatography(GC).Carbon monoxide adsorption on the oxide layer resulted in U4f peak shifting to the lower binding energy.The content of oxygen in the oxide is decreased and the atomic ratio (O/U) is decreased by 7 2%.The amount of carbon dioxide in the atmosphere after the surface reaction is increased by 11 0%.The investigation indicates that the surface layer can prevent the further oxidation uranium metal in the atmosphere of carbon monxide. |
