Kinetic and thermodynamic study of the oxidative catalytic degradation of tartrazine in the presence of oxone® and cobalt supported chitosan-derived carbon-montmorillonite

Abstract

Catalytic degradation of Tartrazine in the presence of Oxone® activated by Co-supported chitosan derived carbon-montmorillonite as catalyst was investigated. The catalyst was synthetized using impregnation-carbonization method. The carbonization temperature was 500 °C. The catalytic experiments were performed at different temperatures in range from 25 °C to 40 °C in order to determinate kinetics parameters. The kinetics data showed best fit with the first-order kinetics model. The activation energy of the investigated degradation process was calculated according to the Arrhenius equation.
