Zusammenfassung

Die spektralphotometrische FIA-Analyse folgender Verbindungen wird beschrieben: Chloramin-T, Dichloramin-T, Dibromamin-T, Bromamin-T, Chloramin-B, Dichloramin-B, Dibroamin-B, Bromamin-B und Dichloramin-N. Ein vereinfachtes 2-Kanal-FIA-Gerät wird benutzt. Trägerlösungen sind KI-Stärke (5.0∶0.5%) und 1 M Schwefelsäure, die vor der Injektion gemischt werden. Ein Probendurchsatz von 280h−1 wurde erreicht. Einflüsse von Reagenskonzentrationen, Fließparametern und Störsubstanzen wurden untersucht. Die untersuchten Konzentrationen lagen im Bereich von 1–60 ppm.

Summary

Flow-injection determination of chloramine-T, dichloramine-T, dibromamine-T, bromamine-T, chloramine-B, dichloramine-B, dibromamine-B, bromamine-B and dichloramine-N in solution, through a spectrophotometric procedure is described. A simplified flow-injection apparatus with a two-channel system is employed. The carrier streams are starch-KI mixture (0.5∶5.0%) and 1 M H2SO4 and are merged before injection of haloamine. A sampling frequency of 280h−1 has been achieved. The effect of reagent concentrations, flow parameters and interferents on the analysis has been investigated. Concentrations of haloamines were in the range of 1–60 ppm.
