Poly (acrylamide-acrylic Acid)/multi-walled carbon nanotubes composite [P(AAm-AA)/MWCNTs] was prepared by gamma radiation to initiate the copolymerization of AAm and AA onto MWCNTs surface. The structural characteristics were confirmed by FT-IR, SEM, XRD, TGA and DTA. The particle size distribution was determined by dynamic light scattering (DLS). [P(AAm-AA)/MWCNTs] was used to study the adsorption efficiency of Sc from natural calcium by batch technique at different concentrations of HCl and/or HNO acid solutions. No-carrier-added Sc (III) was separated from Ca(II) on [P(AAm-AA)/MWCNTs] column matrix. The elution efficiency of about 80 ± 1.5% was attained for Sc(III) using 1M HNO. Three quality control tests, radionuclidic, radiochemical and chemical purities were investigated to emphasis that Sc secure for use in nuclear medicine.
通过γ辐射引发丙烯酰胺（AAm）和丙烯酸（AA）在多壁碳纳米管（MWCNTs）表面的共聚反应，制备了聚（丙烯酰胺 - 丙烯酸）/多壁碳纳米管复合材料[P(AAm - AA)/MWCNTs]。通过傅里叶变换红外光谱（FT - IR）、扫描电子显微镜（SEM）、X射线衍射（XRD）、热重分析（TGA）和差热分析（DTA）对其结构特征进行了确认。通过动态光散射（DLS）测定了粒径分布。采用分批技术，在不同浓度的盐酸和/或硝酸溶液中，研究了[P(AAm - AA)/MWCNTs]对天然钙中钪（Sc）的吸附效率。在[P(AAm - AA)/MWCNTs]柱基质上，从钙（II）中分离出无载体添加的钪（III）。使用1M硝酸时，钪（III）的洗脱效率达到约80±1.5%。研究了放射性核素、放射化学和化学纯度这三项质量控制测试，以强调钪在核医学中的使用安全性。
