High Selectivity and Reusability of Biomass-Based Adsorbent for Chloramphenicol Removal

Recently, biomass-based materials have attracted increasing attention because of their advantages of low cost, environment-friendly and nonpollution. Herein, the feasibility of using corn stalk biomass fiber (CF) and Fe<sub>3</sub>O<sub>4</sub> embedded chitosan (CS) as a nov...
