| 摘 要： | 矿物表面的吸附位点类型与数量决定了其对重金属离子的吸附特性,但氧化锰矿物的结构变化对表面位点,以及吸附特性的影响并不清楚.本研究通过X-射线衍射（XRD）、X-射线光电子能谱（XPS）、等温吸附等技术和方法对比分析了不同锰氧化度（AOS）酸性水钠锰矿对Pb2＋、Cu2＋、Zn2＋、Cd2＋的吸附特点,并探讨了水钠锰矿锰...

| Abstract: | Adsorption characteristics of mineral surface for heavy metal ions are largely determined by the type and amount of surface adsorption sites.However,the effects of substructure variance in manganese oxide on the adsorption sites and adsorption characteristics remain unclear.Adsorption experiments and powder X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS) were combined to examine the adsorption characteristics of Pb2+,Cu2+,Zn2+ and Cd2+ sequestration by birnessites with different Mn average oxid... |
