AbstractIntroduction:Amongst the environmental problems, environmental pollution by heavy metal can be pointed. Theaim of this work is to investigate adsorbing Cadmium (II) a brown alga Fucus serratus and its uptakeby gram-positive bacteria Bacillus sp. Biological methods in comparison with conventional chemicaland physical methods have higher efficiency.Material & Methods:In this study, isotherm and kinetics of cadmium (II) uptake by bacteria and algae in batch reactor isstudied. Langmuir equation based on the maximum rate of uptake of cadmium (II) in bacteria andalgae is achieved. The bacillus sp selected in Tehran, and algae brown Fucus serratus harvested fromPonic city in ocean Atlantic in France.Results & discussion:This study has shown cadmium (II) uptakes, equilibrium time for algae is about 240 minutes and forbacteria is about 10 minutes respectively. The adsorption equilibrium date was well described byLangmuir equation. The maximum capacity has been extrapolated to 0/45, 0/85 mmol /g for bacillusand F. serratus respectively. All these observation indicate that, this biomass (alga) could be a suitablesorbent for the removal of cadmium from wastewaters.
