英文摘要	three zeolitic imidazolate frameworks (zif-8, zif-90 and zif-93) were investigated for adsorption of 5-hydroxymethylfurfural (hmf) from aqueous solution. the equilibrium uptake of hmf decreased following the order of zif-8 (465 mg g(-1)) > zif-90 (307 mg g(-1))> zif-93 (279 mg g(-1)), in accordance with the hydrophobicity of the frameworks. the adsorption equilibrium data were found to follow langmuir adsorption model. the sorption kinetics could be well described by the pseudo-second-order kinetic equation. the hmf-loacled zifs could be fully regenerated with ethanol as the desorption solvent. selective adsorption of hmf from hmf/fructose/water mixtures was also carried out the uptake of hmf remained unchanged, with no observable adsorption of fructose. in liquid phase breakthrough experiments, the uptake of hmf on zif-8 in column was consistent with the batch study. furthermore, the zif-8 packed column could be regenerated effectively and recycled with no discernible loss of adsorption capacity. these findings confirm that zif-8 can be employed as an effective and reusable adsorbent for i-imf recovery from aqueous solution.
