褐藻酸钕配合物的研究

Study on the Neodymium Alginate Coordination Polymer

引入稀土金属离子钕 ( ) ,合成了褐藻酸钕 ( )配位聚合物 ,并用 FT-IR、 XPS、 DTA-TG、电导率等分析手段对配位聚合物进行表征 ,证明了 Nd3+与褐藻酸的配位作用 ,并测得 Nd3+与褐藻酸单体单元的配位比为 1∶ 3 .

The Nd 3+ was inducted to compound the neodymium alginate coordination polymer. The structure and properties of the neodymium alginate coordination polymer were characterized by FT-IR, XPS, DTA-TG and electrical conductivity methods. It showed that there is certain coordination between Nd 3+ and sodium alginate. It is concluded that in the neodymium alginate coordination polymer the Nd ion is coordinated with three sodium alginate units.
