| Abstract | The Moroccan coastlines are known to be rich in marine algae species. Among these seaweed species; Bifurcaria bifurcata with its important biomass has been employed as a new adsorbent for the removal of copper in aqueous solution. Indeed, adsorption tests showed that the equilibrium is established after 60 minutes. Our experimental results demonstrate that the adsorption of copper on the algae is dependent on the pH of the solution and the initial concentration of copper. The adsorption capacity was determined using the Langmuir and the Freundlich isotherms. The maximum adsorption capacity is 101,9 mg.g -1 . The kinetic studies carried out showed that the adsorption of copper by the algae follows pseudo-second order kinetic model with high R 2 values. |
