<p>The invention relates to a method of air cleaning by removal of gaaseous impurities, in particular of sulphur and nitrogen oxides, carbon monooxide and ozone, by letting the medium to be cleaned stream along the surface of reactor plates. The air to be cleaned is set to between 15 DEG C and 85 DEG C and then made to stream along the surface of reactor plates whose active component consists of solidified mixture of urea, cyanuric acid, and amide of allophanic acid, thus producing the gaseous impurities fixation and/or their reaction with urea and/or with amide of allophanic acid and/or with cyanuric acid and achieving the removal or reduction of the gaseous impurities in the cleaned air.</p> |
