【摘要】 介绍了以镍片为基体材料依次将三种聚合物聚丙烯酸、聚丙烯腈和丙烯腈-乙烯基二茂铁共聚物自组装成高分子膜,并与一定浓度的盐酸羟胺反应制成偕胺肟基螯合基团修饰电极。在自配硝酸铀酰溶液中吸附一定时间,把吸附后的螯合电极放在电解质溶液中作阳极,不锈钢片作阴极,选择合适电压进行脱附铀。用扫描电镜对吸/脱附铀后的电极进行表征,用X射线能谱仪(EDS)检测了吸/脱附后电极表面铀元素含量。结果表明:当相对电压为-1.6V时,可脱附掉吸附的铀;含有二茂铁基团的电极表面产生明显的取向性结构。
【Abstract】 In this thesis,PAA,P(AN-co-AA) and P(AN-co-Fc) were coated on the nickel by self-assembly in turn.Then the coating was reacted with hydroxylamine hydrochloridedirectly to make chelating electrode which contained amidoxime-groups.The electrode wascharacterized by SEM.Uranium,its element concentration of uranium was analyzed by EDS.The uranium escaped from electrode when the appropriate voltage was -1.6V.The surface of electrode which contained ferrocene-group had tropism structure very obviously.
