褐藻酸镨配位聚合物的合成与性质

Synthesis and Properties of the Pr(Ⅲ) Alginate Coordination Polymer

本文首次将稀土金属离子镨引入 ,合成褐藻酸镨 ( )的配位聚合物 ,并用 FT- IR、XPS、TG- DTA、荧光和电导率等分析手段对配位聚合物进行表征 ,证明了 Pr( )与褐藻酸的配位作用 ,并测定了 Pr( )与褐藻酸单体单元的配位比为 1∶ 3。

The praseodymium ion was first inducted to compound the Pr(Ⅲ) alginate coordination polymer.FT IR,XPS,TG DTA,fluorescence and electrical conductivity methods characterized the structure and properties of the Pr(Ⅲ) alginate coordination polymer.It showed that there is certain coordination between Pr(Ⅲ) and sodium alginate.It is concluded that in the Pr(Ⅲ) alginate coordination polymer the Pr ion is coordinated with three sodium alginate units.
