英文摘要：

Three kinds of mesoporous carbon including CMK-3, Cubic Ia3d mesoporous carbon and lamellar mesoporous carbon MMC were used as adsorbents, and the removal efficiency of methylene blue （MB） from aqueous solution by them was investigated. The adsorption parameters for Langmuir and Freundlich isotherm models were determinod for these mesoporous carbons. Both isotherms were suitable models to analyze the equilibrium data for the methylene blue adsorption. However, the Langmuir model fitted better than the Freundlich model. The adsorption kinetics was tested with pseudo- first-order and pseudo-second-order reaction model. The pseudo-second-order kinetic, model provided better correlation of the experimental data compared with the pseudo-first-order modal. The adsorption rate constants were 0.007 3, 0.002 0 and 0.004 8 g/（mg·min）, respectively. MorevoVer, physical interaction was the removal mechanism of all these kinds of mesoporous carbon for methylene blue. The results indicated that CMK-3 had the highest adsorption capacity among the three kinds ofmesoporous carbon, and adsorption capacity reached 3.067 g/g.
