Summary

The possibilities of extraction chromatography are investigated for the separation of impurities from high-purity CdTe and ZnSe. The conditions of a quantitative separation of the impurities are determined. As a result of the investigations the techniques are developed for neutron activation analysis of CdTe and spectral analysis of ZnSe, the impurity-detection limits being from 10−5% to 10−7%.

Zusammenfassung

Die Möglichkeiten der Extraktions-Chromatographie für die Anreicherung von Mikrobeimengungen in hochreinem CdTe und ZnSe wurden untersucht. Dazu wurden die Bedingungen der quantitativen Trennung von Mikrobeimengungen in Cd, Te und Zn ermittelt.

Als Ergebnis der Untersuchungen wurden Methoden der Neutronen-Aktivierungsanalyse von ZnSe ausgearbeitet. Bei der Kombination der extraktions-chromatographischen Anreicherung mit diesem Analyseverfahren beträgt die Bestimmungsgrenze für Mikrobeimengungen 10−5−10−7%.
