The Adsorption Performance of Furfural Residue for Menthylene Blue

The adsorption performance of Menthylene blue from aqueous solution by furfural residue was studied. The results show that the adsorption of Menthylene blue on furfural residue reached equilibration by 60 minutes. The removal efficiency of Menthylene blue in aqueous solution on furfural residue of Menthylene blue achieved the 95.38% in 50mL 200mg.L-1 Menthylene blue aqueous solution with adding 4g/L furfural residue. The temperature had an effect on the removing of the Menthylene blue on furfural residue, and the adsorption of furfural residue to menthylene blue was decalescence reaction. The relationship between adsorbing capacity (qe) and equilibrium mass concentration (ρe) is in accordance with the isothermal adsorption equations of Freundlich and Langmuir.
