The macroporous adsorption resin synthesized in this experiment uses cullulose as monomer, adipoyl dichlorid as crosslinker, and cyclohexane as porogenic agent, which three corsslink and polymerize each other, forming the porous skeletal structure. The cellulose processing procedure is as follow: prepare alkali cellulose; crosslink the cellulose (etherification); etherify the cellulose; and functionalize the cellulose. By assaying the perssad characterization of the macroporous resin obtained in this experiment with Fourier infrared spectrometer, we observe hydroxyl group and ester group in the spectrogram. Observing the spectrogram, we find hydroxyl group, indicating that the hydroxyl group in the cellulose has not reacted fully, while the ester group in the spectrogram showing that the ester group has reacted fully with the cellulose. After the aperture characterization for the produced resin with scanning electron microscope (SEM), we find there are unevenly distributed apertures on different levels, which means that new macroporous resin has been synthesized. This paper taking rutin as the adsorbate explores the propertis of static adsorption and desorption of the synthetic macroporous resin, and the influence on its adsorption capability under different situations. The adsorption data shows that the adsorption of rutin on the very resin conforms to the Freundlich isothermal adsorption equation.
