Nanotechnology’s Potential for Detecting Heavy Metals in Water

Abstract

Organic and inorganic contaminants, toxic elements, and non-dissolving compounds are among the toxins found in sewage. Heavy metal ion contamination of effluent is seen as a severe ecological issue in modern civilization. This contaminant seriously threatens the planet. Consequently, it is necessary to develop new and cutting-edge systems and procedures for their eradication. The use of Nanoscience is practically ubiquitous in research and innovation. This also helps in the search for solutions to a variety of environmental issues, particularly water toxicity. It is getting more difficult to develop extremely sophisticated, innovative water remedies because the existing methods cannot keep up with the increased demand for reducing toxic metal concentrations in potable water and municipal wastewater. This research discusses four types of metalloid analysis methods based on nanotechnology: colorimetric, fluorescence, electrochemical, and bio-sensing technologies. This study aims to give academics and industry a current assessment and recommendations for developing nanotechnology and nanomaterials for identifying heavy metals in water.
