从IR、ESR 和XPS的测试结果可知,Ni2 + 或La3+ 与壳聚糖(CS) 链节单元上的氨基N 和仲羟基O发生配位反应,形成CS- Ni2 + 或CS- La3 + 配位聚合物膜。通过电导率研究其配位数,发现Ni2 + 或La3 + 可与壳聚糖的3 个或5 个链节单元配位。根据以上的实验可推定中心离子Ni2+ 与壳聚糖3 个链节单元上的氨基N 和仲羟基O 结合,形成六配位的CS- Ni 配位聚合物;La3 + 与壳聚糖5 个链节单元上的氨基N 和仲羟基O配位形成十配位的CS- La 配位聚合物。从IR、ESR 和XPS的测试结果可知,Ni2 + 或La3+ 与壳聚糖(CS) 链节单元上的氨基N 和仲羟基O发生配位反应,形成CS- Ni2 + 或CS- La3 + 配位聚合物膜。通过电导率研究其配位数,发现Ni2 + 或La3 + 可与壳聚糖的3 个或5 个链节单元配位。根据以上的实验可推定中心离子Ni2+ 与壳聚糖3 个链节单元上的氨基N 和仲羟基O 结合,形成六配位的CS- Ni 配位聚合物;La3 + 与壳聚糖5 个链节单元上的氨基N 和仲羟基O配位形成十配位的CS- La 配位聚合物。
The results of IR, ESR and XPS show that Ni2 + or La3 + coordinated with amino group N and secondary hydroxyl group O on chitosan (CS) unit to form CS-Ni2 + or CS-La3 + Polymer film. The conductivity of its coordination number and found that Ni2 + or La3 + with chitosan 3 or 5 units of coordination unit. Based on the above experiments, it can be inferred that the central ion Ni2 + combines with amino group N and secondary hydroxyl group O on the three units of chitosan to form a six-coordinated CS-Ni coordination polymer. La3 + and chitosan The amino group N on the unit of a unit is coordinated with the secondary hydroxyl group O to form a ten-coordinated CS-La coordination polymer.
