Insights on the advanced processes for treatment of inorganic water pollutants

Abstract

A remarkable increase in the discharge of inorganic pollutants globally from various sources such as mines, industries, or agricultural lands is a major threat to the environment. Development of novel methodologies to mitigate the effects caused by inorganic pollutants in water is crucial in addressing environmental issues. In this regard, various biological sources as nanosorbents and biosensors are venerated as superior entities for the detection and removal of inorganic contaminants. This chapter summarizes the utility of marine bacterial melanin- and fungal-based selenium nanoparticles for the adsorption and further reports endophytic fungal–based ZnS and PbS nanoparticles for the detection of inorganic pollutants from the aqueous systems; moreover, it gives a perspective on current challenges for the removal of contaminants. © 2020 Elsevier Inc.
