AbstractTwo series of chitosan-clay nanocomposites were synthesized using commercial (CLOISITE® Na+) and Na+-enriched Serbian clay from seldom investigated locality Meji Do. The samples were characterized by X-raydiffraction and intercalation of chitosan into bilayer structures was confirmed for particular chitosan/clay ratio in both series of chitosan-clay naonocomposites. Reactivity of chitosan-smectite biointerfaces vs. alkylammonium-clay interfaces in adsorption process was compared using textile dye Reactive Black 5 (RB5) as adsorbate. Chitosan-clay naonocomposites had similar adsorption uptake, being more than three times higher than adsorption uptake of commercial alkylammonium-clay CLOISITE® 30B.The Langmuir adsorption model was found to be appropriate for all investigated adsorbents.
