Montmorillonite-and cellulose-adsorbed 3,6-diaminoacridine are prepared. The adsorption isotherm studies show that while 3,6-diaminoacridine molecules are adsorbed in the interlayer spaces of the montmorillonite clay, the dye molecules are adsorbed on the surface of cellulose. Quenching studies reveal that the Al3+ ions of the aluminosilicate layers of the clay also quench the excited state emission of the adsorbed 3,6-diaminoacridine.
