Adsorption of heavy metal ions (Cu2+ and Pb2+) on various samples of a manganese-zinc nano ferrospinel of composition Mn0.7Zn0.3Fe2O4, produced by the coprecipitation method, was studied. Samples of the starting ferrospinel and that modified with zinc and obtained in the presence of thermally treated agricultural wastes of cereal crops were examined. It was shown that all the three samples are effective sorbents. It was also found that the adsorption process on these sorbents is of complex type, depending on the nature of a metal ion being sorbed.
