| Abstract: | We determined ammonium ion phy separately and compared principle, in precipitation water with Spectrophotometry and Ion chromatogra- standard curve and detection limit of the two methods. The results showed that determining results of standard samples and water samples with the two methods could all reach demand, the determining results were coincident. Ion chromatography is efficient, rapid and accurate. It can determine different cations simultaneously. |
