| Abstract: | The zeolite-based adsorbent with high crystallinity and purity was synthesized by self-transformation of coal gangue in vapor phase of ethylamine and water at a range of 373K-400K,and the preliminary study on its adsorption feature was made.Its adsorption isotherm to phenol was obtained.Results indicated that the adsorbent synthesized from the transformation process was gray,had better adsorption,and the proper adsorb temperature and larger specific surface area were effective means to increase its adsorption. |
