Summary

An electrophoretic study of the platinum metals, as Pt2+, Pt4+, Os4+, Ir4+, Ru3+, Rh3+, Au3+ and Pd2+ reveals that quite a large number of electrolytes effectively separate microgram amounts of ternary and quaternary mixtures of the ions into distinct zones. The voltages are maintained at 100 and 200 V for a period of three hours. The sequences of separation are tabulated.

Zusammenfassung

Die elektrophoretische Untersuchung der Platinmetalle Pt2+, Pt4+, Os4+, Ir4+, Ru3+, Rh3+, Au3+ und Pd2+ ergab, daß zahlreiche Elektrolyte zur Auftrennung von Mikrogrammengen ternärer und quarternärer Mischungen dieser Ionen in scharfe Zonen geeignet sind. Die Spannung wurde dabei auf 100 bis 200 V für 3 Stunden gehalten. Die Reihenfolge der Trennung wurde in Tabellen angegeben.

Résumé

Une étude par électrophorèse des métaux de la mine du platine, tels que Pt2+, Pt4+, Os4+, Ir4+, Ru3+. Au3+ et Pd2+, montre qu'un grand nombre d'électrolytes sépare en zones nettement distinctes des ions en mélanges ternaires et quaternaires, en quantités micro. On maintient la tension à 100 et 200 V pendant 3 heures. On présente sous forme de tableaux l'ordre de la séparation.
