The adsorption of the HgCl2 of different concentrations by colloids such as dry gels of ferric hydroxide, silica gel, aluminium hydroxide and acticarbon was investigated in order to study the nature of the adsorption of HgCl2. It is found that at dilute concentrations of HgCl2 the adsorption tends to be apolar, while at higher concentrations the adsorption is polar. The addition of a strong electrolyte such as sodium chloride retards the adsorption of HgCl2 due to the formation of complex anions of mercury.
