The heattreated coal was prepared in an inert atmosphere at 800°C. The adsorption dynamics that include batch contacttime study, kinetics along with adsorption isotherms were carried out. The study shows that heattreated coal is a suitable adsorbent and can be used for the decolourization of pulp and paper mill effluent streams.

The fuel use by the paperpulp industry may represent about 2% of the total coal burned and the industry's share in airborne mercury pollution amounts to just that. Paperpulp mills discharge only a very small amount of mercury (about ...
