Study on the column process of adsorption decolorization for monosodium glutamate solution in fluidized beds

The adsorption decolorization of monosodium glutamate solution employed in multiple column fluidized beds in a series is studied. The equilibrium data, the mass transfer kinetics, and fluid flow parameters are determined. A mathematics model taking into account the effects of particle size classification, particle size distribution, external and internal diffusions, and axial mixing in the liquid and solid phases is proposed, and the simulated results are in good agreement with the experimental data.
