抄録

A method for the determination of trace amounts of ammonia and lower amines in the atmosphere was studied. Samples were collected at a flow rate of 6 l/min on a glass fiber filter (area of filter is 19.6 cm2) impregnated with a mixture of aqueous solutions of 8% oxalic acid and 1% glycerin. Ammonia and lower amines caught by this filter was extracted with water, and 1 ml of the extract was introduced into an ion chromatograph. Collection efficiencies of both ammonia and lower amines were nearly 100 % both in the above sampling conditions. Both ammonia and lower amines are recovered at almost 100 % efficiency, irrespective of the quantities added to the oxalic acid-glycerin. This technique was simple and collection and extraction efficiencies were good. The coefficient of variation of analysis was less than 5%. Samples collected were able to be kept for at least 6 days without any losses of ammonia and lower amines.
