2D and 3D carbon-based adsorbents for an efficient removal of HgII ions: A review

Today, mercury contamination is recognised as one of the most severe issues concerning human health and the environment. Newer methodologies are being developed and implemented for the removal of mercury from industrial wastewater. Among all, solid-liquid adsorption is perceived as the most widely accepted technique on the grounds of simplicity and efficacy. This review highlights published work on the adsorption of Hg-II onto carbon-based adsorbents. Detailed writings on thermodynamics, isotherm, and kinetics along with adsorption mechanisms have been covered in this review. The fundamental aim of this review is to make readers informed of the advancements that have been made so far for the mercury removal from wastewater using carbon-based adsorbents.
