	Low cost bentonite clay was chemically modified using magnesium chloride in order to enhance its sulfide removal capacity. The incorporation of Co and Al into bentonite (MB). Batch adsorption experiments were conducted to study and optimize various operational parameters such as adsorbent dose, contact time, pH, and initial sulfide concentration. It was observed that the MB works effectively over wide range of pH and showed a maximum sulfide removal capacity of 2.26mgg-1 at an initial fluoride concentration of 5mg L-1, which is much better than the unmodified bentonite. Desorption study of MB suggest that almost all the loaded fluoride was desorbed (~97\%) using 1M NaOH solution however maximum sulfide removal decreases from 95.47 to 73 (\%) after regeneration. From the experimental results, it may be inferred that chemical modification enhances the sulfide removal efficiency of bentonite and it works as an effective
