Removal and Recovery of Heavy Metal Ions Using Natural Adsorbents
Now a day’s heavy metal pollution has become a serious environmental problem. The presence of heavy metal ions is a major problem due to their toxicity to many life forms on this planet. Therefore the removal of heavy metals from the environment is of special concern due to their persistence. During these days natural adsorbents are most frequently studied and widely applied for the metal contaminated water. Adsorption processes are being widely used by various researchers for the removal of heavy metals from the waste streams. The need for the safe and economical methods for the elimination of heavy metals from contaminated waters has developed the interest of researchers towards the production of low cost adsorbents. Therefore there is an urgent need that all possible sources of agro-based inexpensive adsorbents should be explored and their role for the removal of heavy metals should be studied in detail.
