摘要

Two hypercrosslinked polymeric adsorbents (ZH-01 and Amberlite XAD-4 resin) were employed to remove three kinds of phenolic compounds including phenol

4-nitrophenol and 2

4-dinitrophenol from aqueous solutions. The study was focused on the static equilibrium adsorption behavior

the column dynamic adsorption and desorption profiles. The Freundlich model gave a perfect fitting to the isotherm data. The adsorbing capacities for these three compounds on ZH-01 were higher than those on Amberlite XAD-4 within the temperature range 288-318 K

which was attributed to the large micropore area and 2-carboxybenzoyl functional groups on the network of ZH-01 resin. The adsorption for phenol and 4-nitrophenol on ZH-01 was a physical adsorption process

while for 2

4-dinitrophenol it was a coexistence process of physical adsorption and chemisorption’s transitions. The column test showed the advantages of ZH-01 in the dynamic adsorption processes of phenolic compounds. Being used as the desorption reagent

sodium hydroxide solution showed an excellent performance.
