| Abstract | The current manual NO (x) sampling and analysis method was evaluated. Improved time-integrated sampling and rapid analysis methods were developed. In the new method, the sample gas is drawn through a heated bed of uniquely active, crystalline, Pb02 where NO (x) is quantitatively absorbed. Nitrate ion is later extracted with water and the concentration subsequently determined by a NO3 (-) selective ion electrode. A simple selective precipitation eliminates electrode interferences derived from Pb02 absorption of other combustion products such as HC1, SO (x), HF, and CO. Field tests were conducted at various stationary source sites and the data are presented herein. (NTIS) |
