Abstract: Mercury (Hg) contamination in aquatic environment is of immense hazardous problem posing serious risk of bioaccumulation and biomagnification in organism. In order to prevent the Hg contamination, the present investigation was aimed at characterizing the aqueous Hg adsorption capacity of clay based ceramic (C-ceramic) developed by simple heat activation method for applying as an adsorbent media. To characterize the optimum process parameters influencing the adsorption process, the Hg adsorption studies of C-ceramic were carried out by batch operation method with the function of solution initial pH, contact time, C-ceramic doses and initial Hg concentration. The results obtained from different adsorption experiments were analyzed for adsorption isotherm studies. C-ceramic exhibited the equilibrium state of maximum Hg adsorption at 120 min contact period. The adsorption of Hg was largely increased with increasing initial pH and optimum adsorption was found at pH ~9.0!
3. The Hg adsorption capacity showed a decreasing trend with increasing dose of C-ceramic, whereas a reverse response of adsorption capacity was pronounced with increasing initial Hg concentration. Adsorption data was well described by the Langmuir and the Freundlich isotherm models. Results demonstrated the adsorption capacity of C-ceramic was ~445 ìg/g. From the viewpoints of economical feasibility, availability of ceramic, and simple preparation method, therefore, it can be concluded that C-ceramic might be a low-cost and environmentally sound adsorbent for the treatment of Hg contaminated effluents.
