【摘要】介绍光电子能谱（ＸＰＳ）的基本原理和应用，分析煤系黄铁矿添加ＣａＯ并经超声处理后，Ｃａ＋＋在黄铁矿表面的吸附特性，证明Ｃａ＋＋在黄铁矿表面是主要抑制因素，超声处理可以强化ＣａＯ对煤系黄铁矿的抑制。更多还原

【Abstract】 This paper introduces fundamental theories and application of X ray electronic spectroscopy, analyzes the adsorption of Ca++ on the surface of coal pyrite through the ultrasonic treatment by adding the CaO into the coal pulp. It is proved that the Ca++ on the surface of coal pyrite depress its surface adsorption and so ultrasonic treatment can enhance the depression of pyrite with CaO.更多还原
