Heavy Metal Removal

Figure showing the stepwise procedure for the preparation of bi-sorbents and removal of heavy metals from water.
This research explores the use of indigenous waste plant materials for an easy and cost-effective approach for the removal of heavy metals from water.
Mercury contamination in soil, water and air is associated with potential toxicity to humans and ecosystems. Industrial activities such as coal combustion have led to increased mercury (Hg) concentrations in different environmental media. This review critically evaluates recent developments in technological approaches for the remediation of Hg contaminated soil, water and air, with a focus on emerging materials and innovative technologies. Extensive research on various nanomaterials, such as carbon nanotubes (CNTs), nanosheets and magnetic nanocomposites, for mercury removal are investigated.
