Durability of the PEC system

(A) The performances of the PEC method and the PC method during continuous cyclic runs.

(B) In situ EIS plots of the Ti electrode during the PEC uranium extraction experiment.

(C) SEM image of the Ti electrode after PEC uranium extraction.

(D) SEM image of the Ti electrode after PC uranium extraction.

(E) SEM image of the fresh Ti electrode.

(F) Comparison of the uranium content on different electrodes after PEC and PC uranium extraction operation. Conditions: [U(VI)]0 = 0.05 mM, unadjusted pH (∼4.2), [NaCl] = 20 mM, Ebias = 0.50 V versus SCE.
