偕胺肟基功能聚合物膜电极制备及表征

Preparation and characterization of amidoxime-based functional polymer membrane electrode

N,N-二异氰酸酯胺(HNCD)与二茂铁基聚合物(PGMA-Fca)以自组装的方式组装到铝片基体上,经功能化后得到含有偕胺肟基功能电极,并采用FTIR、1HNMR、SEM等测试方法对合成产物结构及自组装电极表面形貌进行了表征。确定了以四氢呋喃(THF)为溶剂条件下HNCD、PGMA-Fca的最佳组装时间分别为25min、15min。SEM表征结果表明,经偕胺肟化后,偕胺肟基功能聚合物膜电极对铀酰离子具有良好的吸附效果。

The N,N-diisocyanamide (HNCD) and ferrocene-based polymer (PGMA-Fca) were assembled into the aluminum substrate by self-assembly,and functionalized to obtain a functional electrode containing amidoxime.The structure of the synthesized product and the surface morphology of the self-assembled electrode were characterized by FTIR, 1H NMR and SEM.The optimal assembly time of HNCD and PGMA-Fca under DMF was determined to be 25 min and 15 min,respectively.The SEM characterization results show that the amidoxime-based functional polymer membrane electrode has a good adsorption effect on uranyl ions after amidoximation.
