Analytical Control of Atmospheric Air
The quality and duration of life depend on atmospheric air. The most common pollutants of atmospheric air from technogenic sources are gases: carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons and aerosols — suspensions of solid and liquid particles. Air sampling in Barnaul was performed by aspiration method passing the air through absorption device at a certain speed or filling vessels of limited capacity. The method for hydrogen sulfide determination is based on the capture of hydrogen sulphide in the air by film chemisorbent and identifying of the compound formed resulting from the interaction of sulfide ion with N, N-dimethyl-nphenylenediamine and ferric chloride. The method for phenol determination is based on capturing of phenol in the air by film chemisorbent and identifying of the compound resulting from the interaction of phenol with 4-aminoantipyrine and potassium hexacyanoferrate. The method for formaldehyde determination is based on capturing of formaldehyde with acetylacetone in the presence of ammonia resulting in 3,5-diacetyl-1,4-dihydrolutidine forming. The method for sulfur dioxide determination is based on capturing of sulfur dioxide in the air by film chemisorbent and identifying the compounds resulting from the interaction of sulfur dioxide with formaldehyde and magenta.
Key words: contaminants, spot samples, mean daily samples, mean daily concentration, carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons, aerosols
