This study examined Mg/Fe-pyro-hydrochar produced from grape pomace as potential sorbent for Cu2+
ions. Obtained results show that the Mg/Fe-modification increases the adsorption capacity for five times.
To evaluate the effectiveness of produced sorbent, Langmuir, Freundlich, Sips and Redlich-Peterson
isotherm models were applied to batch adsorption results. According to applied models Cu2+ adsorption at
equilibrium fitted the Sips isotherm model, with a maximum achieved capacity of 75 mg/g. Spectroscopic
analysis reveal that oxygenated active sites and aromatic groups on pyro-hydrochar surface participate in
Cu2+ions binding. In general, preliminary findings from this paper offers perspective to effective utilization
of waste biomass as an efficient adsorbents for Cu2+ ions removal.
