Microchimica Acta Aims and scope Submit manuscript

Summary

A method is described for the separation and detection on filter paper of chromium and titanium, using thioglycollic acid and chromotropic acid as reagents. Fiveμg of chromium can be detected in the presence of 100μg of titanium, and 5μg of titanium in the presence of 1000μg of chromium.

Zusammenfassung

Eine Methode zur Trennung und zum Nachweis von Chrom und Titan auf Filterpapier wird beschrieben. Thioglykolsäure und Chromotropsäure dienen hierzu als Reagenzien. 5μg Chrom können neben 100μg Titan und 5μg Titan neben 1000μg Chrom nachgewiesen werden.
