This study investigates the adsorption of methylene blue and eosin Y on opal-cristobalite rocks, and finds that the adsorption amount is determined by the content of amorphous silica and clay minerals in the rocks. The results also show the possibility of accurately determining the amorphous silica content in opal-cristobalite rocks using IR spectroscopy. Higher values of the point of zero charge in opal-cristobalite rocks are associated with lower silicon and aluminum contents, as well as higher total content of alkali and alkaline earth metals.
The adsorption of methylene blue and eosin Y on opal-cristobalite rocks has been studied. The amount of methylene blue and eosin Y adsorbed on opal-cristobalite rocks is determined by the amorphous silica and clay minerals contained in the rocks. The possibility of using the results of IR spectroscopy for accurate determination of the amorphous silica content in opal-cristobalite rocks is shown. For opal-cristobalite rocks, a higher value of the point of zero charge is associated with lower silicon and aluminum contents in them and higher total content of alkali and alkaline earth metals.
