The resin (named FZH33) modified with m-trihydroxybenzene onto the surface of the resin during the post-crossing of chloromethyl low crosslinking macroporous poly-styrene resin was prepared and characterized. This paper focuses on the static equilibrium adsorption behaviors, desorption profiles and the confirmation of chemisorption characteristics, and experimental comparisons of the adsorption properties of FZH33 with NDA150 toward 2,6-dichlorophenol or m-trihydroxybenzene were performed. The result shows that due to the chemisorption effect the adsorption capacities of m-trihydroxybenzene or 2,6-dichlorophenol in FZH33 are more higher than those in NDA150 at the same temperature and initial concentration, and the lowest increment percentage of FZH33 will reach 115.9% and 18.9% for m-trihydroxybenzene and 2,6-dichlorophenol respectively, which shows the adsorption selectivity for adsorbing phenolic compounds. Compared with those of single component system, the highest increment percentage of bicomponent system for adsorbing m-trihydroxybenzene and 2,6-dichlorophenol onto FZH33 will reach 261.7% and 24.5% respectively, and the cooperative adsorption effects in aqueous bicomponent system of m-trihydroxybenzene and 2,6-dichlorophenol onto FZH33 are investigated.
