Abstract:
Objective To develop a sensitive, safe and quick method for determination of ammonia in the air. Methods The air samples collected with multi-hole absorbing tubes were determined by ion chromatography after sampling. Results The recovery rates, precision (relative standard deviation) and detection limit were 97.6%-99.8%, 1.08%-2.93% and 0.05 ?g/ml,respectively. There was no significant difference between this method and chemical method. Conclusion The method is simple, quick, sensitive and suitable for determination of ammonia in the air.
