FIELD: water treatment. SUBSTANCE: invention focuses on removing metal ions and ions of radioactive substances from aqueous solutions. Method includes following stages: contacting solution being treated with particles of magnetic material having polymer outer surface with attached regions capable selectively extract pollutant ions in presence of other ions removal of which is not aimed; separating magnetic material from solution by magnetic filtration method; regenerating isolated magnetic material particles using appropriate regenerating solution; separating regenerated magnetic material particles from regenerating solution; recycling separated magnetic material particles into the first stage. EFFECT: improved process flowsheet. 6 cl, 2 tbl
