Simultaneous adsorption of heavy metals and organic dyes by β-Cyclodextrin-Chitosan based cross-linked adsorbent

Herein, a new adsorbent Nitrilotriacetic acid β-Cyclodextrin-Chitosan (NTA-β-CD-CS) was synthesized for the effective simultaneous removal of dyes and metals. In this process, the β-CD cavities captured Methylene blue (MB) by host/guest contacts, and the remaining functional groups were able to act as adsorption sites for metal ions and Methyl orange (MO). In the single process, the maximum adsorption capacities of NTA-β-CD-CS adsorbent toward...
