Trace determination of nickel by combining paper chromatography with radiometric precipitation

  • Published:
Microchimica Acta Aims and scope Submit manuscript

Summary

A technique combining Chromatographic separation with radiometric precipitation is described in which nickel is determined at theμg to submicrogram range. An appropriate solvent completely isolates nickel from interference on a Chromatographic strip. Nickel is then precipitated as the35S labeled nickel sulfide. Quantitative yields are obtained using radioautography and radiometry.

Zusammenfassung

Ein Verfahren der chromatographischen Trennung und radiometrischen Fällung zur Bestimmung von Nickel in der Größenordnung von Mikrogramm bis Submikrogramm wurde beschrieben. Mit einem geeigneten Lösungsmittel wird Nickel vollständig von allen störenden Faktoren auf einem Chromatogrammstreifen isoliert und dann als Ni35S gefällt. Durch Radioautographie und Radiometrie erhält man quantitative Ergebnisse.
