Heavy metal ions have become an ecotoxicological hazard of prime interest and increasing significance, because of their accumulation in living organisms. In this study, a series of batch laboratory experiments were conducted in order to investigate the feasibility of Enteromorpha sp activated carbon for the removal of chromium from aqueous solution by the adsorption process. Investigation was carried out by studying the influence of initial solution pH, adsorbent dosage, contact time and initial concentration of chromium. The activated carbon produced showed excellent efficiency in removing chromium with percentage removal up to 90 % at low adsorbent dosage of 400mg. The study also showed that the adsorption of chromium by the activated carbon is dependent on the contact time of the adsorbent and the initial metal concentration and pH. The use of Enteromorpha sp for activated carbon also helps in solving the problem of waste water treatment.
