ABSTRACT

The presence of heavy metal ions in water is regarded as a major challenge as well as a great risk for public health. Nanotechnology is termed as an emerging area of science that can resolve a range of environmental tasks by regulating the shape and size of materials at nanoscale. Further, carbon nanomaterials are exceptional owing to their non-hazardous nature, simple biodegradation, extraordinary surface area, and predominantly valuable environmental remediation. Moreover, carbon derivatives are receiving additional consideration because of their significant physicochemical characteristics which can be exploited for the elimination of heavy metals from polluted water. Carbon nanomaterials including graphene and its oxide, fullerenes, carbon nanotubes, and activated carbon have an abundant response for the elimination of heavy metals from wastewater owing to their nanoscale size, accessibility of unlike functionalities, and lastly large surface area; thus, they are simple to be amended chemically and reused. This report provides a study of the most recent advances in the applications of these carbon nanomaterials for heavy metal removal from polluted water, as well as their presentation of environmental remediation. Carbon-based nanomaterials’ toxicological characteristics are also detailed.
