Abstract

The adsorption of tartrazine (T) by montmorillonite (M) and sepiolite (S) is studied in this work. Results show a strong interaction between clays and the colorants because of the cationic exchange and the realignments of the organic molecule when the adsorption takes place. Ultrasound technique (US) improves the colorant adsorption by the clays.

Item Type: Conference or Workshop Item (Paper)
Uncontrolled Keywords: Adsorption, clays, ultrasound technique, tartrazine.
