| Abstract: | A method was developed for detecting ammonia nitrogen in surface water sample by gas-phase molecular absorption spectrometry.The detection limit is 0.020 mg/L,the recovery rate is between 91.3% and 100% with RSD about 0.10% (n=7), and the relative deviation of the parallel samples are between 0.25% and 1.43%.The results showed that the method is sensitive, accurate, simple, reproducible, fast and suitable for the determination of ammonia nitrogen in surface water. |
