Abstract:
Samples of natural bentonite and clinoptilolite modi ed 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 MiLj=S(M = Co(II); Fe(III); and Pd(II); L = NO− 3 ; Cl−, and SO2 4−; 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.
