Removal of mercury from aqueous solution using sheep bone charcoal

The carbon derived from sheep bone with zinc chloride activation was applied for the adsorption of mercury (II). The effect of solution temperature, adsorption time, pH value and initial concentration of mercury(II) ions on the adsorption ability was investigated in a bfigatch process mode. The morphology and structure were characterized by scanning electron microscopy and X-ray diffraction. The BET surface area and pore volume of the prepared sheep bone charcoal were 83.98 m(2)/g and 0.246 cm(3)/g, respectively. The equilibrium data were fitted to linear and Freundlich isotherm.
