Adsorption characteristics of modified bentonites for purification of anthocyanin from saffron tepal
Food Science &Nutrition, Volume 12, Issue 11, Page 9136-9150, November 2024.The adsorption isotherms and kinetics of the anthocyanin on the modified bentonites extracted from waste of saffron flower was evaluated. The activation of bentonite by both acid and heat exhibited more adsorption than bentonite modified byonly acid or thermal.
