制备了经间苯三酚进行化学修饰的吸附树脂并进行了红外光谱表征, 以NDA150作为参照, 对比了两种吸附树脂对不同温度下水溶液中间苯三酚、2,6-二氯酚以及间苯三酚/2,6-二氯酚双组分体系的吸附研究, 并探讨了其吸附机理. 结果表明: 在合适的温度下FZH33对溶液中间苯三酚、2,6-二氯酚的吸附过程存在化学吸附效应, 和NDA150相比较, 在相同浓度下, FZH33对溶液中间苯三酚、2,6-二氯酚的静态吸附量显著增加, 静态吸附百分比增量分别最少可达115.9%和18.9%, 显示出对酚类物质的吸附选择性|在一定温度和浓度范围内, 在双组分体系下水溶液中间苯三酚/2,6-二氯酚在FZH33上的吸附具有协同吸附效应, 和单组分相比, FZH33在双组分中对间苯三酚和2,6-二氯酚的静态吸附百分比增量分别最高可达261.7%和24.5%.

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.
