Abstract:
The phenomenon of 17O, 18O enrichment in the surface layer of CdO was investigated by means of temperature-programmed desorption-ion-trap detector (TPD-ITD), quadrupole mass spectrometer(QMS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction(XRD)etc.The results obtained showed that the Cd(OH)2-CdCO3 surface layer of CdO possesses the ability of selective inclusion of oxygen molecules containing 17O, 18O in air.
Key words:  CdO, Oxygen isotope enrichment, Ion-trap detector, Coadsorption of CO2 and O2

摘要:
利用热脱附-离子捕获检测器(TPD-ITD)、四极质谱(QMS)、X光电子能谱(XPS)、X光衍射(XRD)等方法,研究了在CdO表面层中17O、18O的富集现象。所获结果显示,CdO表面Cd(OH)2-CdCO3层在形成过程中对含17O、18O的氧分子有选择包结能力。
