| titleOfInvention | Nitrate nitrogen quantification method, anion quantification method and tristate nitrogen quantification method |
| abstract | An object of the present invention is to grasp the decomposition behavior of an organic substance simultaneously with the treatment behavior of ammonia nitrogen in a sample without being affected by oxalic acid contained in the sample. According to the method for quantifying nitrate nitrogen of the present invention, nitrate ions in a sample are quantified by anion chromatography using a carbonate-based eluent as an eluent. Alternatively, nitrite ions and nitrate ions in the sample are quantified by anion chromatography using a carbonate-based eluent as the eluent. The anion quantification method of the present invention quantifies oxalate ion, nitrite ion and nitrate ion in a sample by anion chromatography using a carbonic acid-based eluent as an eluent. In the method for quantifying trinitrogen according to the present invention, oxalate ion, nitrite ion and nitrate ion in a sample are quantified by anion chromatography using a carbonaceous eluent as an eluent, and then the sample is converted to a cation. The sample is subjected to chromatograph to quantify ammonium ions in the sample. [Selection] Figure 1 |
