| Abstract: | AQ2 discrete analyzers were utilized to measure the NH3-N in the surface water. The testing result was almost the same as that of traditional Nessler＇s reagent colorimetric method and two testing methods had good linear relation. The method was easy to operate and analyze quickly with less reagent. Between 0.25 ~5.00 mg/L, detection limit of the NH~-N was 0. 019 rag/L, RSD and recovery with adding standard sample was between l. 647 8% ~5. 865 1% and 94.1% ~109.4% ,respectively. |
