The adsorption technique using chemically treated powder of bark of Acacia arabica was applied for the removal of toxic heavy metals from polluted waste water. The extent of adsorption found to be dependent on the pH and the time of contact. The adsorbent is effective for the quantitative removal of various toxic metals from the contaminated aqueous sample. The method is quite feasible, economic and time saving. The concentration of unadsorbed metals were determined by atomic absorption spectrophotometer. The applicability of bark of Acacia arbica was tested for the removal of Cu2+, Pb2+, Zn2+ and Cd2+ ions from aqueous sampl
