- Determination of Trace Amounts of Alcohols in Ambient Air and Exhaust gas from Vehicles using Formation of Alkyl Nitrite
抄録
A gas chromatographic determination method for alcohols at ppb levels has been developed based on the rapid formation of an alkyl nitrite in the heterogenous reaction of alcohols with NO2 on cleaned Pyrex glass surface. Methyl and ethyl alcohols at several tens ppb and isopropyl alcohol at hundreds ppb were detected in the polluted air at the road sides. Methyl alcohol at several thousand ppb and ethyl n-propyl, isopropyl, isobutyl alcohols at hundreds ppb were detected in the exhaust gas from gasoline engines. Methyl and ethyl nitrites were formed in the dark or photochemical reaction of these alcohols with NO2 in the exhaust gas.
