Batch adsorption experiments were carried out for the removal of Lead from its aqueous solution using Ulva fasciata sp. a marine green algae as adsorbent. The adsorption of lead by Ulva fasciata sp. was investigated as a function of pH, contact time, initial metal and adsorbent concentrations and adsorbent size. The results indicate that the amount of lead adsorbed increased with increase in metal concentration, weight of biomass and pH of the aqueous phase. The dynamic data fitted to the pseudo-second order kinetic model. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. The experimental adsorption data were fitted to the Langmuir adsorption model.
