Automatic photometric titration of fluoride with thorium nitrate and alizarin S as indicator
Description
The photometric titration of fluoride with thorium nitrate and Alizarin S as indicator has been automated and optimized for fluoride levels between 1 and 20mg/85ml solution. The interference of several ions has been investigated. This procedure is particularly useful for the determination of fluoride after fusion with peroxides as fluxing agents. (orig.)
Abstract (German)
Fuer Fluoridgehalte zwischen 1 und 20mg in 85ml Loesung wurde die photometrische Titration mit Thoriumnitrat und Alizarin S automatisiert und die Arbeitsbedingungen optimiert. Ausgewaehlte Matrixeinfluesse werden eingehender untersucht. Dieses Verfahren ist besonders fuer die Bestimmung von Fluorid aus Peroxid-Aufschluessen geeignet. (orig.)Additional details
