摘要：
Ion-exclusion chromatography of NH4+ has been investigated on an anion-exchange resin (OH-). NH4+ was chromatograhed by ion exclusion as NH4OH formed by anion exchange, and monitored with a flow coulometric detector for the detection of OH-, and / or with a conductometric detector. The chromatographic conditions for the separation of NH4+ from diverse cations, the separation mechanism and each detector response are discussed. This method has been applied to the determination of NH4+ in sewage and river water. The result obtained agree well with those obtained by the phenate method. © 1979.
