本文报导聚乙烯吡咯烷酮和聚丙烯酸与某些金属或稀土元素的三元络合物的XPS研究。结果证实了络合物的形成,并提出了其可能的配位结构,同时发现金属离子结合能位移与Pauling电负性之间的有趣关系。
This paper reports the XPS studies of the ternary complex of polyvinylpyrrolidone and polyacrylic acid with some metals or rare earth elements. The results confirmed the formation of the complex and proposed its possible coordination structure. At the same time, we found an interesting relationship between the displacement of the metal ion binding energy and the Pauling electronegativity.
