Microchimica Acta Aims and scope Submit manuscript

Summary

Complexometric determinations of praseodymium, neodymium and samarium as representative members of the rare earths with Alizarin Red S, Thoron, and Murexide as ohelatochrome indicators have been investigated. The studies include the determination of optimum pH range, concentration range and other conditions required for the analysis of these metals.

Zusammenfassung

Die komplexometrische Bestimmung von Pr, Nd und Sm als typische Vertreter der Seltenen Erden mit Alizarinrot S, Thoron oder Murexid als chelatochrome Indikatoren wurde untersucht. Optimales pH-Bereich, Konzentrationsbereich und andere Parameter wurden geprüft.
