摘要
研究了复合功能超高交联树脂对水溶液中对苯二酚的静态吸附热力学特征,结果表明:超高交联树脂上引入适量的胺基,可明显地提高树脂的吸附容量。该类树脂对对苯二酚的吸附为自发的放热过程,属于物理吸附过程。
Three hypercrosslinked polymeric adsorbents AH-1,AH-2 and AH-3,which were chemically modified by amination with dimethylamine,were employed to remove hydroquinone from aqueous solution through static experiments.A comparison of adsorption behaviors against the three functional resins,the hypercrosslinked polymeric adsorbent NDA-100 with no tertiary amino groups was made.It was found that the adsorption capacities of hydroquinone increased notablely on the hypercrosslinked resins after amination.The adsorptions of hydroqinone on the four hypercrosslinked resins were all spontaneous exothermic processes with physical characters.
