In this research, an innovative biomass derived spongy adsorbent was fabricated by adopting dialdehyde cellulose nanocrystals (DCNC) as crosslinking and reinforcing building block, which showed high mechanical strength, satisfying adsorption performance and good recyclability. The improved shape integrity and specific surface area resulted from DCNC incorporation contribute to high adsorption performance of this sponge. Adsorption behaviors of the adsorbent were comprehensively studied. The q for Pb and Cd by the adsorbent could reach as high as 767 and 517 mg/g, respectively. Also, this adsorbent showed excellent recyclability. In addition, the adsorbent exhibited satisfying fixed-bed column adsorption performance. Thus, it could be considered as promising high efficiency adsorbent.
