ADSORPTION KINETICS AT DIFFERENT CONCENTRATIONS OF Cu (II) ONTO LOCAL MARL

Abstract

Copper is known to be commonly used heavy metals. This metal, which find many useful applications in our life, are very harmful if they are discharged into natural water resources and many pose finally a serious health hazard .Therefore it is necessary to treat copper containing wastewater before discharging in to water streams.In this work ;kinetic investigations were carried out to evaluate the applicabiIity of used marl found in located in Oum-El-Bouaghi region (Algeria) as a low-cost adsorbent to the removal of copper ions from aqueous solutions.Marl was characterized with FTIR and SEM. The effects of initial concentration and temperature on adsorption of Cu(II) were investigated.,also Kinetic aspects of sorption of Cu(II)on marl has been studied through batch sorption experiments and test of experimental data with pseudo-first and - second order rate models
