Influence of pH and electric field on HgCl adsorption in clay-water systems and its environmental implications.

Mercury and its compounds, particularly mercury chloride (HgCl), are highly toxic and persistent environmental pollutants. Understanding the adsorption behavior of HgCl in clay-water systems is essential for developing effective mercury remediation strategies. This study investigates the effects of pH and background cations on the adsorption kinetics, adsorption energy, and dipole moment of HgCl in montmorillonite clay systems.
