Abstract: In recent years, removal of heavy metals from contaminated water has become a major topic due to the toxicological problems caused by the toxic metals to the environment and to human health. Among the various removal methods, adsorption has been proven to be an efficient technology, while its large-scale application is limited by the high cost of the adsorbent. Under this situation, some raw agricultural residues materials,as low-cost adsorbents, were tested to evaluate their efficiency in the removal of heavy metals. The main objective of the present studywas to investigate the feasibility of biochars, resulted from date palms and cotton stalks slow pyrolysis process, as adsorbents for Co (II) and Ni (II) removal from polluted drainage water. The two biochars (i.e. date palms and cotton stalks) were characterized and investigated for Co (II) and Ni (II)removal from polluted water from a main drain. Similarly, activated carbon (A.C.) from the date palms residues was prepared by thermal analysis as adsorbent and used for comparison with the two biochars. The results indicated that the original product biochars from slow pyrolysis process might be used as inexpensive adsorbents for water purification.
