Abstract |
The Griess method (Saltzman procedure) has been used in air pollution work to determine NO2 in laboratory and field operations and it has been adapted for use in automatic instrumentation. In this latter investigation it was shown that alkyl nitrites also react with the reagent in the automatic nitrogen dioxide analyzer used. It appeared of interest to determine the reactivity of the alkyl nitrites directly without also having to consider absorption efficiencies. The amount of reaction on a micromole basis of n-butyl nitrite, t-butyl nitrite, n-amyl nitrite, and i-amyl nitrite was determined for comparison with the reactivity of sodium nitrite and nitrogen dioxide. |
