Samples of natural bentonite and clinoptilolite modified with copper(II), iron(III), and palladium(II) were characterized by both X-ray phase and the Fourier transform infrared spectral methods. The activity of monometallic compositions M_{i}L_{j}/S(M = Co(II), Fe(III), and Pd(II); L = NO₃¯, Cl¯, and SO₄²¯; S = N-CLI or N-Bent) in the reaction with sulfur dioxide was found to depend on the nature of both a metal ion and a support. For bimetallic compositions Cu(II)-Fe(III) and Cu(II)-Pd(II) based on the natural aluminosilicates, a certain synergism in the action of metals forming these pairs towards the reaction of sulfur dioxide oxidation with oxygen was determined.
