Summary

The rate and the rate constant of the process of complexing of In3+ and Ga3+ were evaluated in media containing hydrochloric acid, sulfuric acid or nitric acid and different organic solvents. It was established that the rate of the process is maximum in aqueous-acid environments (without presence of organic additions), in almost all investigated cases in the first minutes of the reaction.

Zusammenfassung

Es wurden die Komplexierungsgeschwindigkeiten von In3+ und Ga3+ in Lösungsmittelsystemen mit Salzsäure, Schwefelsäure oder Salpetersäure und verschiedenen organischen Lösungsmitteln gemessen. Dabei konnte gezeigt werden, daß die Geschwindigkeit in wäßrig-saurem Medium (ohne Zusätzen von organischen Verbindungen) und dann fast immer in den ersten Minuten der Reaktion am größten ist.
