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 C. 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 activated energy of adsorption is 2.589 kJ/mol.
