The adsorption of the heavy metal ions over both the adsorbents was found to follow Langmuir and Freundlich adsorption isotherm models. It was observed that the adsorption capacity of rice husk increased after treated with nitric acid. The pseudo first-order, pseudo second-order, second order and intra-particle diffusion models were used to analyze the kinetic data and the rate constants were evaluated. The kinetic adsorption data fitted the pseudo second-order kinetic model well and also followed the intra-particle diffusion model up to 90 min, but diffusion is not the only rate controlling step. 2009-07-31T08:38:09Z 2009-07-31T08:38:09Z 2007-02 Article Electronic Journal of Environmental, Agricultural and Food Chemistry, vol.6 (2), 2007 pages 764-1774. 1579-4377 http://ejeafche.uvigo.es/index.php?option=com_docman&Itemid=33 http://hdl.handle.net/123456789/6620 en University of Vigo |
