Determination of the concentration of silicon dioxide in crystal by potentiometric titration with a fluoride-selective electrode

Autor: E. P. Lashuk, S. M. Chesnokova

Publikováno v: Glass and Ceramics. 51:149-153

The possibility of using the reaction of fluoride ions and fluoride complexes with aluminum complexonate in the presence of an excess of complexone III was investigated for determining the concentration of silicon dioxide in crystal after rapid decom

Fast photometric determination of iron impurity in red lead and litharge

Autor: S. M. Chesnokova, E. P. Grishina

Publikováno v: Glass and Ceramics. 52:77-78

A method for fast photometric determination of iron impurity in red lead and litharge is suggested. The method is based on the use of reactions of complexation of iron(II) and 2,2′-dipyridyl or 1,10-phenanthroline after dissolution of a specimen in
