In this study we analyze the Cu(II) biosorption characteristics of the dead biomass of the Chilean brown macroalgae Durvillaea antarctica as a function of initial metal ion concentration and pH. We determined an equilibrium time of 120 min and a maximum biosorption performance at pH 5.0. The isotherms data at optimum pH best fitted with the Dubinin–Radushkevish model, showing a maximum capacity for...
