氧化树脂的制备及其对水溶液中2，4-二氯苯酚的吸附研究

Study on preparation of resene and its adsorbing 2,4-dichlorophenol in aqueous solutions

用H2O2或HNO3氧化的方法制备了新型吸附树脂ZH-07和ZH-08,同时研究了它们对不同温度下水溶液中2,4-二氯苯酚的静态吸附和脱附特征,并对其吸附机理进行了探讨。结果表明,经氧化后的树脂ZH-07和ZH-08对水溶液中2,4-二氯苯酚的吸附过程存在化学吸附作用,可以提高它们对水溶液中2,4,-二氯苯酚的吸附容量。

New polymeric adsorbents oxidized by oxydol （ZH-07） or nitric acid（ZH-08）group for adsorbing 2,4-dichlorophenol were prepared, The static adsorption characteristics for 2,4-dichlorophenol onto them at different temperatures were studied and their adsorption mechanism were further investigated and compared. The result shows that chemisoption will be in existence in the adsorption process of 2,4-dichlorophenol in aqueous solutions with NDA150 oxidized and the adsorption capacities of 2,4-dichlorophenol in aqueous solutions with resene will be improved.
