Abstract
Spectrophotometric method for determination of methyl alcohol in the atmosphere has been developed. The method is based on adsorption of methyl alcohol on activated charcoal, desorption with carbon tetrachloride, oxidation of methyl alcohol to formaldehyde and spectrophotometric determination with chromotropic acid. Good precision has been obtained. Coefficient of variation was found to be +/- 4.96% for n = 24. The minimum determinable amount of methyl alcohol in the atmosphere was found to be 0.005 mg/m3 by passing 720 l of air.
