Sorption and desorption of Cd, Cu and Pb using biomass from an eutrophized habitat in monometallic and bimetallic systems

► The eutrophized biomass can be used for decontaminating effluents with heavy metals. ► The sorption kinetics in monometallic systems was very fast. ► In bimetallic systems this was slower because the competence between metal cations. ► The metal recovery was possible with HCl and with NaHCO3. ► With NaHCO3, the sorption metal uptake increased for the reused biomass.
