Biosorption is a promising alternative method to treat industrial effluents, mainly because of its low cost and high metal binding capacity. In this work, Zinc and Chromium biosorption process by Sargassum sp. seaweed biomass was studied. The work considered the determination parameters of Zinc and Chromium sorption such as pH, temperature, agitation speed and biomass size. The optimum conditions were: pH3, temperature (303k) room temperature, biomass size 0.5mm and agitation speed 150rpm. The maximum uptake of Chromium and Zinc is 65% and 53% respectively. The kinetic study revealed that the adsorption of Chromium and zinc by Sargassum sp. fitted the Langmuir isotherm.
