dc.description.abstractIn this study adsorption properties of adsorbent prepared from the seeds and leaves of Moringa oleifera were studied. The adsorbents that were prepared used to remove heavy metals ions Aluminum and Arsenic ions from water. The determination methods for the Aluminum and Arsenic ions were EDTA back titration and Iodiometric titration. Different parameters that effect the adsorption were optimized with the help of these methods dose, pH, temperature, initial metal concentration and effect of seeds and leaves. It was established that adsorbent prepared from Moringa seeds have great efficiency for removal as compared to leaves and seeds have great efficiency for removal of aluminum ions as compared to arsenic ions. As the initial metal concentration increase removal efficiency decrease in both metals. The highest removal efficiency obtained in both metals at the 10 (mg/L) conc. The pH effect was direct on efficiency of adsorbent as the pH increases, removal efficiency also increases and at pH =6 removal of both metals become higher. As the concentration of adsorbent dose increases, the removal of heavy metals aluminium and arsenic also increases and the highest removal efficiency for both metals obtained at 1.1g. As the temperature increased the removal efficiency also increased in both metals. The highest removal efficiency obtained at 70(°C). Seeds give higher removal percentage in both metals as compared to seeds because seeds contain more amount of carbohydrates, proteins and essential amino acids as compared to leaves.
