FIELD: chemistry.
SUBSTANCE: invention relates to preparation of inorganic sorbents. Proposed is method of producing aluminosilicate adsorbent comprising preparing a heterogeneous composition containing aluminum powder, crystalline sodium metasilicate, Na2SiO3·9H2O and aqueous solution of metal salt selected from copper, calcium, nickel, cobalt, or silver. Weight ratio of said components is 1:3:10. Stirring resulting mixture is carried out for 10 minutes at room temperature. Then allow to dry in air at room temperature for 7 days.
EFFECT: invention provides sorbent with high capacity in relation to heavy metals and radionuclides.
