Title

KINETIC AND THERMODYNAMIC STUDIES OF ADSORPTION OF 4-CHLORO-2-NITROPHENOL ON NANO-TIO2

Pages

  33-37

Abstract

 ADSORPTION capacity of 4-CHLORO-2-NITROPHENOL (4C2NP) onto nano-TiO2 from aqueous solutions was investigated in a batch system by considering the effects of various parameters like contact time, nano-TiO2 dosage, initial pH and initial 4C2NP concentration. Optimum conditions for 4C2NP ADSORPTION were found to be initial pH» 2, nano-TiO2 dose» 0.01 g and equilibrium time» 1 h. The ADSORPTION KINETIC data were analyzed using pseudo-first and pseudo-second order models. It was found that the pseudo-second-order KINETIC model was the most appropriate model, describing the ADSORPTION KINETICs.The THERMODYNAMIC parameters such as DGo, DHo and DSo were computed from the experimental data.These values show that the ADSORPTION of 4C2NP onto nano-TiO2 is spontaneous and endothermic.
