Summary

In the presence ofn-tetradecyltrimethylammonium bromide aluminium reacts with Bromopyrogallol Red (BPR) to form a ternary complex, in which the molar ratio of aluminium ot BPR is 1∶2. The method is suitable for the determination of traces of aluminium in natural waters. The ternary complex has an absorbance maximum at 623 mm with molar absorptivity 5.05×104 l · mole−1 · cm−1. Beer's law is obeyed over the range 0.1–0.4μg/ml of aluminium. Iron(II) and iron(III) interfere but can be masked with hydroxylammonium chloride and 1,10-phenanthroline. Aluminium can be determined at about the 100-μg/l level in river water.

Zusammenfassung

In Gegenwart vonn-Tetradecyltrimethylammoniumbromid reagiert Aluminium mit Brompyrogallolrot (BPR) unter Bildung eines ternären Komplexes im Verhältnis 1∶2 (Al∶BPR). Das Verfahren eignet sich für die Bestimmung von Aluminium in natürlichen Wässern. Die Absorbanz des Komplexes bei 623 nm beträgt 5.05×104l·mol−1·cm−1. Bei 0.1-0.4μg Al/ml wird das Beersche Gesetz erfüllt. Eisen(II) und (III) stören zwar, lassen sich aber mit Hydroxylammoniumchlorid und 1,10-Phenanthrolin maskieren. In Flußwasser kann Al in der Größenordnung 100μg/l bestimmt werden.
