Abstract

Heavy metal contamination in water is a serious issue that puts people’s health at risk. Carbon nanomaterials are gaining popularity as a result of their superior physicochemical features, which can be used to remediate heavy metalcontaminated water more effectively. Because of their large surface area, nanoscale size, and availability of various functionalities, carbon nanomaterials, such as carbon nanotubes, fullerenes, graphene, graphene oxide, and activated carbon, have great potential for heavy metal removal from water. Toxic metal pollution (heavy metals, radioactive metals, etc.) is one of the most serious global problems; hence, removing toxic metals from contaminated water appears to be very vital. Nanotechnology plays a critical role in environmental monitoring and pollution management to address these concerns. Carbon nanotubes (CNTs) and their composites have gained a lot of attention because of their high adsorption capability in removing metals from contaminated water or enriching metals from wastewater. By selectively functionalizing CNTs with organic ligands, ...
