【摘要】 借助于光电子能谱（ＸＰＳ）及俄歇电子能谱（ＡＥＳ）测试，系统地研究了糊精在氧化矿及盐类矿物表面的作用行为．发现糊精在赤铁矿、金红石、方解石和重晶石表面作用前后晶格金属元素键合状态发生了显著变化，其本质为化学作用，而糊精在萤石表面作用前后，Ｃａ的结合能及俄歇参数变化较小，化学作用较弱，更接近于氢键等物理作用。更多还原

【Abstract】 A systematic investigation on interactions between dextrin and salt-type minerals has been carried out with X-ray Photoelectron Spectroscopic(XPS)and Auger Electron Spec troscopic(AES)measurements The result demonstrates that before and after interaction the election binding energy of lattice metal ions and Auger parameters of the minerals such as hematite,rutile caleite and barite show a significant chemical shift ehile that of fluorite shows a very week one,indicating the formers arc chemical interact and the latter is probably physicall adsorption in nature.更多还原
