Microbial and Natural Products Chemistry Department, National Research Centre, Dokki, Cairo, Egypt, EG aut Removal of Pb2+ by Biomass of Marine Algae [Elektronische Daten] [A. A. Hamdy] New biosorbent material derived from ubiquitous marine algae has been examined in packed-bed flow for Pb2+ removal through sorption columns. Mixed biomass of marine algae has been used, consisting of representative species of the following algae: Ulva lactuca (green algae), Jania rubens (red algae), and Sargassum asperifolium (brown algae). A mixture of these three species showed a promising removal capacity for Pb2+ from aqueous solution. Lead uptake up to 281.8 mg/g dry algal mixture was observed. Equilibrium was achieved after 120 min. No significant effect of changing the flow rate on the removal capacity was noticed. It was found that Langmuir model expresses the system at pH 4. Mineral acids exhibited good elution properties (a mean of 93%) for recovery of sorbed biomass ions as compared with the tested alkalies (about 60%).
