✦ Synopsis

Ion-exclusion chromatography of NH, + has been investigated on an anionexchange resin (OH-). NH,+ was chromatographed by ion exclusion as NH40H

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 NH,+ from diverse cations, the separation mechanism and each detector response are discussed. This method has been applied to the determination of NH,* in sewage and river water. The results obtained agree well with those obtained by the phenate method.

The distribution coefficient (Ko) of trace zinc in 1 M NaCl solution on an aminophosphonate-chelating resin Duolite C467 increased with pH to a peak value close to 200000 ml/g at pH about 6. At higher pH values the KD dropped to 25 000 ml/g due to competition of zinc hydrolysis. Increasing NaCl conc
