Zusammenfassung Untersuchungen der Adsorption von Kongorot an wä\riges Chromoxid zeigt 1. da\ dies ein exothermer Proze\ ist. 2. die Adsorptionswärmen niedrig sind, mit wachsender Bedeckung ansteigen und dann ein Maximum durchlaufen, das auf heterogene Oberfläche hindeutet.Es handelt sich offensichtlich um eine Chemisorption. 3. Die Art der Präparation ändert den Charakter des Oxids von basisch zu sauer.
Notes:
Summary From the study of Congo red adsorption on hydrous chromium oxide it is concluded that: 1. The adsorption of Congo red by hydrous oxide is an exothermal process; 2. The heat of adsorption values are low, it increases with increasing coverage and then passes from a maxima showing that the surface is heterogeneous. It further suggests that the adsorption of Congo red by hydrous chromium oxide is a chemisorption process. 3. It has been further noticed that the mode of preparation, changes the character of the hydrous oxide as a basic or as an acidic mordant.
