Abstract:
|
The sorption performance of hyper-cross-linked
Macronet resin (MN200) to remove phenol and aniline from
aqueous solution has been evaluated. Fixed bed column experiments
were undertaken to obtain the breakthrough curves in both
single and binary solutions. The film-surface diffusivity model has
been used to predict the single (phenol and aniline) fixed bed
breakthrough curves by using the Langmuir and Freundlich single
isotherm data to represent the equilibrium. A good description of
the experimental data has been obtained by both isotherms, and the
mass transfer coefficient and the surface diffusivity have been
obtained as optimized parameters for both solutes. The binary
breakthrough curve prediction has been performed by the film
surface diffusion model, incorporating an equilibrium relationship
defined by the extended Langmuir isotherm model and the ideal
sorbed solution theory (IAST). The sum of square errors (SSE) obtained for the IAST approach confirms the good agreement
between the experimental and the predicted breakthrough data and the deviation obtained for the extended Langmuir model.
The surface diffusivities in binary sorption reported a significant difference to those obtained in a single system, indicating that
binary sorption is mainly controlled by the intraparticle diffusion. |
