摘要

Abstract

A novel ZIF-8-CMC hybrid material was fabricated from the hybridization of ZIF-8 and carboxymethylcellulose (CMC) by impregnation method for

-hexane/3-methylpentane separation. The surface properties of ZIF-8 were tailored by introducing CMC into ZIF-8 nanoparticles. In this work

adsorption separation of

-hexane (

HEX) and 3-methylpentane (3MP) on ZIF-8-CMC were investigated by batch vapor-phase adsorption and liquid-phase breakthrough adsorption. The adsorption selectivity of

HEX/3MP reversed from preferable adsorption of

HEX to preferable adsorption of 3MP upon the increasing of CMC containing in the hybrid materials. As the temperature increases

the adsorption amounts of

HEX and 3MP decrease. With the increasing of CMC contents

the

HEX uptake decreased

the uptake capacity of 3MP increased gradually. For liquid-phase breakthrough adsorption

the dynamic adsorption capacity of

HEX also decreased with the increasing of temperature.
