ABSTRACT:

The Bean Plants were used in this work as low cost adsorbent material for removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The samples were prepared and sorted according to the particles diameter by standard sieves 250 - 500 µm. Batch adsorption experiments were carried out to study the adsorption process pH of adsorbent, effect of contact time, effect of adsorbent amount and effect of metal concentration were Investigated in these experiments. The effect of any one of those previously mentioned parameters on the adsorption capacity were studied while the other parameters were kept constant. The maximum adsorption capacities of beans for the removal of selected heavy metals were very high. It is suggested to use it as a low coast adsorbent material to clean up the water in the environment from toxic heavy metals.
