| Abstract |
Trace gaseous HNO3 in air is removed in a laminar flow nylon tube. The HNO3 deposition pattern was obtained by sectioning the tube, extracting with an aqueous solution, and measuring the concentration by ion chromatography. Mass transport analysis of the deposition pattern demonstrated the HNO3 was removed from the air stream at a rate controlled by gaseous diffusion. The HNO3-air diffusion coefficient = 0.116 + or - 0.003 sq cm/s (n = 7) for t = 298 K and p = 1 atm. It exhibited no dependence on relative humidity over the range 5 - 95%. |
