AB  - Herein, the precursor polyphosphazene was synthesized by the polymerization of 
      hexachlorocyclotriphosphazene (HCCP) and bis(4-hydroxyphenyl) sulfone (BPS). The 
      adsorbent which was codoped with N, P and S (amidate-CS) was developed from the 
      precursor by using the carbonization method. The images of Scanning electron 
      microscope (SEM) and Transmission electron microscope (TEM) indicate that the 
      amidate-CS possessed porous graphene-like carbon lamellar structure. The 
      excellent behaviors with respect to kinetics (120 min for equilibrium) and 
      thermodynamics (maximum removal of 290 mg/g when pH was at 6.0) revealed the 
      outstanding performance of amidate-CS in removing U(VI), which is due to the 
      functional groups and strong covalent bonds between heteroatoms and uranyl ions. 
      The adsorption of amidate-CS followed the pseudo-second-order kinetic and 
      Langmuir adsorption model. The thermodynamic parameters indicate that the process 
      was spontaneous and endothermic. The adsorption and desorption efficiency of 
      amidate-CS had a slight decrease after five cycles, indicating excellent 
      regeneration performance. Overall, the amidate-CS is a prospective candidate for 
      highly selective U(VI) removing.
