Zusammenfassung

Die hochspannungselektrophoretische Wanderung der Halogenokomplexe der Platinmetalle und verschiedener anorganischer Ionen bei Anwendung einfacher Monocarbonsäuren (Ameisensäure, Essigsäure, Chloressigsäure, Trichloressigsäure, Trifluoressigsäure, Glycin), Hydroxycarbonsäuren (Milchsäure, Mandelsäure,α-Hydroxyisobutter säure [α-HIBA], Sulfosalicylsäure) sowie einiger Na-Salze dieser Säuren wurde untersucht und der Einfluß des pH-Werts, der Konzentration der Substanzen und der Befeuchtung der Papierstreifen auf die Wanderung geprüft. Dabei wurde festgestellt, daß neben Trichloressigsäure die Hydroxycarbonsäuren bzw. deren Salze (besondersα-HIBA) für Trennungen platinmetallhaltiger Gemische eingesetzt werden können.

Summary

The high tension electrophoretic migration of the halogen complexes of the platinum metals and various inorganic ions with employment of simple monocarboxylic acids (formic, acetic, chloroacetic, trichloroacetic, trifluoroacetic, glycine) hydroxycarboxylic acids (lactic, mandelic,α-hydroxyisobutyric acid (α-HIBA) sulfosalicylie acid, as well as several sodium salts of these acids, were investigated and the influence of the pH-value, the concentration of the substances and the moistening of the paper strips were tested with respect to the migration. It was found that along with trichloroacetic acid, the hydroxycarboxylic acids or their salts (especiallyα-HIBA) can be introduced for the separation of mixtures containing platinum metals.
