Summary
Stability and composition of the chelate of copper and Chrome Azurol S have been investigated, and suggestions are made for the spectrophotometric determination of copper.
Zusammenfassung
Stabilität und Zusammensetzung des Kupferkomplexes mit Chromazurol S wurden untersucht. Nach Entfernung von Beryllium, Aluminium, der Lanthanide, Titan, Zirkon, Hafnium, Thor, Uran, Eisen, Palladium, Borat, Carbonat, Oxalat und Zitrat kann Kupfer einfach und empfindlich spektrophotometrisch bestimmt werden.
Résumé
On a étudié la stabilité et la composition du complexe que donne le cuivre avec le chromazurol S. Aprés séparation du Be, de l'Al, des lanthanides, de Ti, Zr, Hf, Th, U, Fe, Pd, des borates, carbonates, oxalates et citrates, on peut doser le cuivre par spectrophotométrie, d'une maniére simple et sensible.
