Abstract:A r t i c l e I n f o A b s t r a c t Keywords: Pillared clay, adsorption, indigo carmineClay is plastic in wet conditions where there is an interlayer swelling, but there is no a permanent pore. This shortage can be overcome by converting the natural clay into a pillared clay. Clay pillarization was conducted by intercalation of Al polycation on natural clay followed by calcination. The synthesis results were characterized by an X-ray diffractometer. The indigo carmine adsorption was analyzed by a uv-vis spec… Show more
