| description abstract | Rice-husk ash (RHA) was found to be a good adsorbent for Hg(II) in aqueous solutions. Batch studies indicated that the percent adsorption decreased with increasing initial concentration of Hg(II) and particle size of adsorbent. Twenty g/L of RHA (diameter 37–50 μm) in an aqueous solution of Hg(II) with an initial concentration of 100 mg/L removed 98% of Hg(II). A contact time of 3 hr was found to be optimum. Maximum Hg(II) removal was observed near a pH of 6.0. Adsorption conformed to the Langmuir isotherm. Column experiments indicated that the adsorbed amount of Hg(II) decreased with increasing flow rate and decreasing bed height. | |
