Characterization and performance of the H2BHT polymeric adsorbent. a, b SEM images for the starting material (polyethylene-graft-polyacrylic acid) and the H2BHT adsorbent, respectively. Scale bars, 50 µm. c δ 13C CP/MAS solid-state NMR spectra of H2BHT polymer and H2BHT ligand spun at 15 kHz. d Uranium sorption isotherm (inset displays the linear regression by fitting the equilibrium data with the linear form of the Langmuir adsorption model). All the fits (red lines) have R2 values higher than 0.98. The equilibrium concentration (ppm) of uranyl ions is given for each data point. e Kinetics of uranium removal from aqueous solution with an initial concentration (10 ppm, 400 mL) at pH ~6, and adsorbent material (5 mg)
