International audienceIn this study, easy to manufacture and ecological solid free-formaldehyde phenolic foams were prepared by a mechanical foaming process from mixtures of tannins and lignin alkaline liquor. The resulting biosourced phenolic foams were characterized and examined as bio-adsorbents for heavy metals (Cu2+, Cd2+, Zn2+ and Pb2+) removal from aqueous solutions. Many experimental parameters were investigated to optimize metals adsorption such as solution pH, temperature, initial metal concentration, and metals-foams contact time. The adsorption capacities of studied metals onto biosourced foams reached 46.5, 41, 29.1, and 100.9 mg/g for Cu2+, Cd2+, Zn2+ and Pb2+, respectively. Their adsorption isotherms and kinetics isotherms we...
