| Abstract: | Measurement of the molecular absorbance at 201 nm of the ammonia gas displaced from strongly alkaline solutions containing ammonium ions provides a rapid, sensitive and selective method for the determination of nitrogen. A simple apparatus based on an atomic absorption spectrometer is described. The method can be applied to the determination of the nitrogen content of soil and plant samples. |
