Heavy metal pollution in our water systems has become a global concern. Pollution of heavy metals in water arises from anthropogenic activities such as industrial processes, agricultural runoff, mining, and improper waste disposal. The persistent accumulation of heavy metals in aquatic environments necessitates innovative approaches for remediation. Furthermore, accurate detection and characterization of heavy metals is crucial for proper assessment when evaluating various challenges on water pollution. Emerging applications from the field of nanoscience provide promising developments for both remediation and analytical techniques required for both detection and quantification of heavy metal contaminants. This review provides a comprehensive overview on the current applications of nano-based approaches for heavy metal remediation in water and various analytical techniques based on nanomaterial-based technologies. Important advancement in both removal and characterization of heavy metals provides a holistic outlook on nanomaterials, as well as providing a comprehensive perspective on how nanotechnology can facilitate innovation in water remediation and detection of pollutants.
