一种提高复合功能吸附树脂亲水性并强化其吸附性能的方法
摘要：
本发明公开了一种提高复合功能吸附树脂亲水性并强化其吸附性能的方法。其步骤包括：(A)将氯球胀于硝基苯或二氯乙烷中，加入催化剂，通入氧化剂，逐步升温至20～120℃，通过控制树脂残余氯含量确定反应终点，得到超高交联聚苯乙烯树脂；(B)反应后，抽尽反应母液，用有机溶剂洗涤含氧超高交联聚苯乙烯树脂，然后直接加入功能试剂与树脂内外表面残留氯甲基进一步反应，功能试剂用量为超高交联聚苯乙烯树脂的0.5～3倍，可制得含氧复合功能超高交联聚苯乙烯树脂。本发明可以根据需要在复合功能超高交联聚苯乙烯树脂微孔、中孔和大孔区域都引入含氧功能基团，强化了其在极性溶液中的吸附性能，吸附容量提高10％以上，节约运行成本。
摘要（英）：

The invention discloses a method for improving a composite resin adsorption function and strengthening its hydrophilic properties of adsorption. The steps include: (A) it bulges the chlorine-ball in the nitrobenzene or dichloroethane, and adds the catalyst, and accesses to the oxidant, and gradually warms up to 20 ~ 120deg.C, then it determines the response end by controlling the residual chlorine content of resin to achieve the high crosslinked polystyrene resin. (B) After the reaction, it pumps out the liquor of reaction, and washes the oxygenated high crosslinked polystyrene resin with organic solvent, and then it directly adds a functional reagent to further react with the residue chloromethyl on internal and external surface of resin to achieve the oxygen high crosslinked polystyrene resin. In which, the amount of the functional reagent is 0.5 to 3 times of the high amount of cross-linked polystyrene resin.
