摘要

研究了微波改性蒙脱土吸附苯酚的等温线和动力学。结果表明，在pH7.2条件下，接触时间为1 h，温度为20℃，M-OMt的吸附量为58.14 mg/g。吸附数据与Freundlich等温线吻合较好，吸附动力学与拟二级动力学吻合较好。相关系数(R2)分别为0.9992、0.9999。吸附活化能为2.589 kJ/mol。

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

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.
