Among the various techniques, adsorption is one of the most suitable methods which can be adopted to remove hazardous ions from water and waste water. The development of low cost adsorbent is essential for the benefit of the common people. Experiments were conducted in batch mode to know the removal efficiency of chromium (VI) as a function of size, pH, adsorbent dose, initial concentration and time. The removal efficiency of Cr(VI) was maximum at particle size of 0.46mm, pH-5, adsorbent dose of 2.5%, contact time 120 minutes from the aqueous solution having initial Cr (VI) concentration of 100 mg/L. From this study it is infer that the selected adsorbent is having high potential to remove Cr(VI) and other toxic metal which require further study.
