Abstract

The Saltzmann method is currently used frequently as a method of measuring the nitrogen oxides in the air. However, there are many debates concerning its coefficient (the transformation coefficient from NO2 to HNO2), and the absorption and coloration mechanisms, also, are not yet clear. Studies were made of these points in comparison with the Hygiene Testing Method. Results are reported.
