Abstract

Thus far, properties of clay such as the ion exchange capacity and the particle size have been focused upon as the most important. In the present study, the effect of the location of the charged sites in the clay structure on the adsorbed molecule were investigated. The effects of the charged site location on the aggregation behavior of methylene blue and on the fluorescence behavior of methylviologen were examined. In the case of methylviologen as a dye, the fluorescence intensity was much larger on the clay surface than that in aqueous solution.
