The use of magnetic nanocomposites containing carbon derivatives and biopolymer for aquatic contaminants removal

Abstract

Anthropogenic activities and industrial development are consequences of the increase in the world population occurred in the last century. The result is more generation of waste through textile and metal-mechanic industries mainly by carrying out improper disposal, without proper treatment directly in the environment. This practice is criminal and causes irreversible damages to humans and other animals affected by the contaminants. As a result, the exploration, research, and development of new materials with “green” characteristics as well as new compounds, which is the case of magnetic nanocomposites containing graphene oxide and chitosan in their structure. The present review approaches these materials and their application in process for adsorption of metallic contaminants and dyes. The combination of these nanomaterials presents a potential and promising characteristic in the adsorption processes, demonstrating high efficiency, easy handling, and reusable capacity due their magnetic characteristic and combined properties.
