%X In alkaline solution NH3-N may react with Ness-ler's agent forming a yellow compound. Based on the light absorption property of the formed suspended particle a new method for determining NH3-N by primary-secondary wavelength spectro-photometry was developed. The detection limit of the method for NH3-N is 0.02 mg/L, RSD<2% and the recovery is 93%-105%. The method is suitable for the determination of NH?N natural water and polluted water.
