ABSTRACT

Several materials were used as adsorbents to remove metal ions and other hazardous pollutants from aqueous environments, however natural sources are considered ecological safer, cheaper, and more efficient than physicochemical processes. Marine algal biomass has proven to be highly effective as well as reliable and predictable in the removal of Pb+2, Cu+2 , Cd+2, and Zn+2 from aqueous solutions. Fresh water algae, Chara and Oedogonium and marine water algae, Ulva lactuca, Scinaia furcellata, and Caulerpa racemosa were used for the biosorption study of some heavy metals for live algae was estimated. COD and adsorption isotherms were observed and found that the adsorption of Cr+6,Al+3 and Fe+3 ions at 50ppm and 100 ppm found maximum by Chara, Ulva lactuca, and Caulerpa show maximum adsorption, respectively. In batch reactor studies, Oedogonium shows approximately 78% removal efficiency for chromium ion removal. Keywords: Biosorption, Algae, Heavy metal, Batch reactor, COD
