Abstract

Using crustacean shell wastes to produce chitin/chitosan-based biosorbents has gained increasing attention because of its promising potential for waste recycling and environmental remediation. However, from raw materials to final biosorbents, the traditional acid-alkaline-treated chitin suffered from complicated procedures and serious secondary pollution. In this work, via an integrating one-step environmental-friendly procedure, a novel EDTA-grafted chitin (ECH) was successfully prepared using Portunus trituberculata shells. The obtained biomaterial possessed a three-dimensional porous microstructure and extra functional groups, and showed exceptional adsorption efficiency and reusability for Cu(II) adsorption. The highest Cu(II) removal rate reached 99.4%, while the corresponding adsorption capacity reached 223.70 mg g−1. Moreover, the adsorption data followed better with the Langmuir isotherm model, while it fitted well with both the pseudo-first-order model and the pseudo-second-order kinetics model. Further study suggested that the adsorption mechanisms of Cu(II) by the ECH should be a formation of EDTA–chitin–Cu complex. These findings would enlighten the development of more novel chitin-based biosorbents using crustacean shell wastes via more facile and green ways, as well as their application as biosorbents for environmental restoration.
