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。
The phenomenon of 17 O, 18 O 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-CdCO 3 surface layer of CdO possesses the ability of selective inclusion of oxygen molecules containing 17 O, 18 O in air.
