摘要：
To efficiently remove U(VI) from aqueous solutions, porous polyvinyl alcohol/carboxylated carbon nanotubes/sodium alginate (PPCS) hydrogel microspheres were prepared using the physical cross-linking method. The successful formation of highly porous PPCS hydrogel microspheres was confirmed by SEM and BET. Moreover, PPCS hydrogel microspheres were recovered from aqueous solutions more easily than carbon nanotubes. The main mechanism of PPCS for U(VI) removal may be the chelation of hydroxyl and carboxyl groups. PPCS may be ...
