Annotation

The study examined the thermal analysis of polysilicic acid gels modified with solutions of different concentrations of ethanolamine in absolute ethanol. The effect of temperature on the sorption properties of these compounds at 30 ° C, 50 ° C and 80 ° C was also analyzed thermally.

Keywords
