International Journal of Environment and Waste Management (IJEWM), Vol. 8, No. 3/4, 2011

Abstract: The potential to remove lead (II) ions from aqueous solutions using natural kaolinite was investigated. The effects of several parameters including solution pH, adsorbent dose, ionic strength and solution temperature on adsorption were examined. The sorption data followed the Freundlich, Langmuir and Dubinin-Radushkevich isotherms. The adsorption process was spontaneous and endothermic in nature. Dynamics of the sorption process were studied and the values of rate constant of adsorption were calculated. The kaolinite can be used to remove lead (II) ions from aqueous solutions.
