Adsorbents Used for Removal of Mercury from Aqueous Solutions: A Review

A lot of Researchers have addressed removing mercury as a pollutant from the wastewaters of several industries. Heavy metals are being removed from wastewater through adsorption on activated carbon, which is becoming additional popular. Although commercial activated carbon is the ideal adsorbent for pollutant elimination, its extensive usage is limited because of its high cost, encouraging researchers to explore alternative effective and low-cost adsorbents. These include activated carbon, polymers, nanoparticles, and low-cost adsorbents. For the remediation of water from mercury, polymers, as well as nanoparticles, which are very effective adsorbents, can be employed. According to a literature review of the most recently published research, polymers and nanoparticles have exhibited exceptional mercury removal capabilities. The present study reviews the different works in which the different adsorbents materials were used to eliminate mercury in the solutions.
