Microchimica Acta Aims and scope Submit manuscript

Summary

A method for the microdetermination of copper, cobalt and nickel from a mixture containing 40 metal ions by circular thin-layer Chromatographic technique is described. The procedure is simple; the chromatoplate takes about 2 minutes for its development and other metal ions do not interfere with the determination. The recovery of copper, cobalt and nickel is better than 98%. The apparatus for the concentration of test solution before TLC analysis is also described.

Zusammenfassung

Die Mikrobestimmung von Kupfer, Kobalt und Nickel in Gemischen von 40 verschiedenen Metallionen im Wege der zirkulären Dünnschichtchromatographie wurde beschrieben. Die Vorgangsweise ist einfach; die Entwicklung der Chromatogramme erfordert 2 Minuten, fremde Metallionen stören nicht. Die Ausbeute an Kupfer, Kobalt und Nickel ist besser als 98%. Ein Gerät für das Einengen der Probelösung vor der DC-Analyse wurde gleichfalls beschrieben.
