摘要
一种新型杯芳烃衍生物偕胺肟基修饰亚甲基桥杯[8]芳烃(C8A-AO)首次成功合成,并通过处理得到C8A-AO纳米颗粒。使用核磁氢谱和碳谱、红外光谱、扫描电镜、X射线光电子能谱等方法对其进行了表征。考察了C8A-AO在不同pH值、接触时间和温度等条件下对铀酰离子的吸附能力,研究了其在模拟海水中对铀酰离子的选择性吸附能力,以期C8A-AO在核工业海水提铀领域发挥其应用价值。
A novel calixarene derivative,amidoxime group modified methylene bridged calix[8]arene(C8A-AO),was successfully synthesized and treated to obtain C8A-AO nanoparticles for the first time.It was characterized by 1H NMR,C-NMR,IR,SEM and XPS.The adsorption capacity of C8A-AO for uranyl ion at different pH,contact time and temperature was investigated.The selective adsorption capacity of C8A-AO for uranyl ion in simulated seawater was studied,in order to play its application value in the field of uranium extraction from seawater of nuclear industry.
