Zusammenfassung

Silicium wird direkt in der Probelösung als Molybdänblau nach Reduktion mit 1-Amino-2-naphtholsulfonsäure-(4) bestimmt. Siliciumgehalte bis herab zu 5 ppm können mit einem Fehler von höchstens ±5% bestimmt werden.

Summary

A procedure for the determination of small amounts of silicon in uranium dioxide is described. Silicon is determined directly in the sample solution by means of the molybdenum blue method with 1-amino-2-naphthol-4 sulphonic acid as a reducing agent. Contents down to 5 ppm can be determined with an error not exceeding ±5%.
