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
