Gangue For The Preparation Of Zeolite-based Adsorbent

The study that porous glass beads were synthesized using the gangue was used as raw in this experiment to study the process that the zeolite-based adsorbent with high crystallinity and purity was synthesized by self-transformation of gangue in vapor phase of ethylamine and water at a range of 373K-400K.and the preliminary study on its adsorption feature was made. The adsorption properties of the zeolite-based adsorbent were characterized by adsorption isotherm, specific surface area and pore distribution with the help of N₂ adsorption. The zeolite-based adsorbent was investigated with XRD and small-opening consideration etc. And the adsorption isotherm of it to phenol was obtained. Results indicated that the zeolite-based adsorbent synthesized from the transformation process was gray and had better adsorption. The paper pointed out that the proper adsorb temperature and larger specific surface area were effective means to increase the adsorption of the zeolite-based adsorbent.
