Biosorption capacity of three common macrophytes viz., Eichornia crassipes, Pistia stratiotes and Lemna minor) was evaluated with respect to the removal of the heavy metal, lead (Pb) from aqueous solution. The influence of various parameters such as pH (5 to 8), biomass weight, initial metal ion concentration (0.25 to1.25 ppm/L) and contact time (3 to 15 days) on biosorption efficiencies were determined. Results indicated that the Maximum metal removal efficiency reached 77.2% for E. crassipes at pH 7 due to high sorption of metal, plant fresh weight increased to 26.8g. The biosorption of lead by P. stratiotes increased with increasing pH of aqueous solution. At 7.5 pH maximum heavy metal, 53% was removed. L. minor shown highest absorption 19.8% at 7 the lead concentration was accumulated to 26% for L. minor, 34% for P. stratiotes and 36% for E. crassipes respectively, after 15 days and reached at equilibrium. These results led to refer that the macroalgal biomass could form a potential, eco-friendly, cost effective and safe alternative biosorbent for fine tuning of waste water treatment.
