A novel chelating adsorbent, modified sawdust (MS), was synthesized by grafting quaternary ammonium on the cellulose of sawdust, was first designed for high performance U(VI) removal. The property MS was characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffractometer, and Fourier transform infrared spectroscopy. Removal efficiency of U(VI) for MS and raw sawdust (RS) was evaluated at different dosages, pHs, contact times, and temperatures. Results showed that maximum U(VI) removal efficiencies of 99.7% and 72.8% for...
