Novel BTBP [bis-(1,2,4-triazin-3-yl)-2,2'-bipyridine]/BTPhen [bis-(1,2,4-triazin-3-yl)-1,10-phenanthroline] functionalized silica gels have been developed to extract minor actinides, lanthanides and other fission products. BTPhen functionalized silica gel is capable of near-quantitative removal of Am(iii) in the presence of Eu(iii) from aqueous HNO, while BTBP functionalized silica gel is able to remove problematic corrosion and fission products that are found in PUREX raffinates.
新型双（1,2,4 - 三嗪 - 3 - 基）- 2,2'-联吡啶/双（1,2,4 - 三嗪 - 3 - 基）- 1,10 - 菲咯啉功能化硅胶已被开发用于萃取次锕系元素、镧系元素和其他裂变产物。双（1,2,4 - 三嗪 - 3 - 基）- 1,10 - 菲咯啉功能化硅胶能够在硝酸水溶液中，在铕（iii）存在的情况下近乎定量地去除镅（iii），而双（1,2,4 - 三嗪 - 3 - 基）- 2,2'-联吡啶功能化硅胶能够去除普雷克斯萃余液中存在的有问题的腐蚀产物和裂变产物。
