Fig. 7

a Schematic diagram of TFPT-BTAN-AO regeneration detection and extraction of UO22+. b The UO22+ adsorption capacity (left axis) and elution efficiency (right axis) of TFPT-BTAN-AO in six successive adsorption–desorption cycles. c FT-IR spectra of TFPT-BTAN-AO, TFPT-BTAN-AO after extraction of UO22+, and TFPT-BTAN-AO after desorption of UO22+ by the Na2CO3 (1.0 mol L−1) aqueous solution. Error bars represent S.D. n = 3 independent experiments.
