摘要：
This paper presents the potential use of the organic-inorganic immobilized mixtures green algae Scenedesmus armatus bentonite (hybrid adsorbent) for removal of Cd2+ from aqueous solution. Experimental parameters affecting the adsorption process such as biomass dosage, Cd2+ initial concentration, pH and temperature were studied. An increase of biomass dosage and heavy metal concentration led to an increase of adsorption capacity values, while low pH values and increased temperatures led to a decrease of adsorption capacity values. Langmuir and Freundlich isotherm models describe well the adsorption process, and kinetic of the process was best described by the pseudo-second-order model.
