Nanocomposite Chitosan@graphene Oxide-Based Aerogel Beads for Anionic and Cationic Dye Removal: Synthesis, Characterizations, and Complexed Interfacial Interactions in Batch and Column Studies.

ABSTRACT: One of the greatest global threats to the environment and human health is the persistent pollution of water. Adsorption is a recognized remediation method that effectively and efficiently removes pollutants from water. In this work, nanocomposite aerogel beads of chitosan-graphene oxide (CS/GO) and chitosan-reduced graphene oxide (CS/rGO) were synthesized by a simple three-step procedure and evaluated as an adsorbent material for water purification. In particular, two model pollutant molecules, namely, indigo carmine (IC, anionic dye) and methylene blue (MB, cationic dye), were used to study the adsorption behavior of the developed materials by kinetics and isothermal analyses in batch configuration. Adsorption kinetics follows the Elovich model well, while adsorption isotherms are better
