| Abstract: | The paper presents the results of application of the stoichiographic method of differential dissolution (DD) to the analysis of modified aluminosilicate and zirconium silicate fiberglass materials (FGM) and related catalysts. Na-Al-Si and Na-Zr-Si FGM have been studied after sodium leaching-out and subsequent modification with Al, Co, and Pt additives. The conditions of detection, identification, and determination of different forms of FGM modifiers and the analysis of the surface of these samples are provided. The DD method has been used for the precise correction of the composition of the fiber glass sample surface. |
