Scholarcy highlights

  • In this paper, a kind of graphene gel loading TBP inside, named as G-TBP-Gel was prepared via by mildly reducing the graphene oxide sheets in TBP/GO/water emulsion using ascorbic acid, which is facile and time-consuming
  • The TBP droplets are fixed in the pores, and the total volume of TBP occupies nearly 90% volume of the G-TBP-Gel
  • We studied the capacities and distribution ratios of G-TBP-Gel in the application of uranium extraction under different conditions
  • The residual oxygenated groups on the reduced graphene oxide sheets construct a network of water nano-channels, via which uranyl migrates in the process of extraction or stripping
  • Compared with traditional liquid-liquid extraction, the rates of extraction or stripping are much slower due to the structural factors, which still need promotion in the future
