Abstract

The review discusses the removal of mercury (Hg) from wastewater by advanced oxidation processes (AOPs) and adsorption. The Hg adsorption in batch and column method was described, and the mechanism was explained, followed by the equilibrium and kinetic modelling. Furthermore, thermodynamic molecular modelling and simulation of Hg adsorption were discussed. The results showed that the removal of Hg from the aqueous solution by AOPs was successfully applied. Some of the future perspectives include enhancing the efficiency of the AOPs for the removal of Hg. The efficiency of available technologies for the removal of heavy metals in general and Hg in particular, depend on three criteria, namely efficacy, cost, suitability, and conditions of application. Langmuir and Freundlich isotherm models are best-fit and also pseudo second order kinetic model.
