Study on Isotherms and Kinetics of Adsorption of Phenol on Microwave Organic Modified Montmorillonite

Abstract

Isotherms and kinetics of adsorption of phenol on microwave organic modified montmorillonite were investigated. The results show that the adsorption capacity of M-OMt was determined as 58.14 mg/g at the conditions of pH7.2 contact time of 1 hour and temperature of 20¡ãC. The adsorption data is a good fit with Freundlich isotherm, and the adsorption kinetics is in better agreement with pseudo-second order kinetics. The corresponding correlation coefficients (R2)are 0.9992 and 0.9999, respectively. And the activted energy of adsorption is 2.589 kJ/mol.
