Przeanalizowano przydatność kaolinu pochodzącego z lokalnego polskiego złoża jako ekonomicznego adsorbenta mogącego znaleźć zastosowanie do oczyszczania ścieków. Jako przykładowy adsorbat wybrano barwnik kationowy. Zbadano kinetykę procesu, wyznaczono izotermy adsorbcji dla surowego kaolinu i próbek modyfikowanych oraz zależność adsobcji od pH roztworu.

EN

Industrial kaolin from a local Polish deposit has been examined as a cost-effective adsorbent for cationic dyes, using methylene blue as a probe. The adsorption process reaches equilibrium during 30 minutes and corresponds to the second-order kinetics. Adsorption isotherms for the raw and modified kaolin samples have been determined. Relationship between solution pH and the adsorption has been determined as well. The acid treated kaolin as well as calcined one proved to have somewhat decreased adsorption capacity whereas alkaline modified one had increased sorption capacity.
