Bio-adsorption of heavy metals by mangrove biomass has been valued as a potential alternative to the existing physiochemical technologies for detoxification and recovery of valuable heavy metals from waste waters. In this context the efficacy of mangrove leaf powder Avicennia marina (MLP) as bio adsorbent for removal of divalent metal ion Chromium was investigated. The particle size of the powder was kept constant at 1mm. Adsorption of the heavy metal was studied under varying MLP amount and Time while pH (4.0) and a temperature (37o C) were kept constant. With a defined calibration curve adsorption of chromium was estimated with diphenyl carbazide absorption method using colorimeter (visible). Increase in concentration of MLP paralleled with time showed maximum adsorption of chromium. These results indicated that mangrove leaf powder (MLP) can be used as low cost adsorbent for the removal of chromium from aqueous solutions.
