摘　　要：以含氧极性芳香小分子苯乙醚和乙酰苯胺与氯甲醚反应,合成了一种既含有醚键又含有酰胺健的极性超高交联吸附树脂ZH-1,极性树脂ZH-1的比表面积为114.72 m2/g,平均孔径为1.682 nm.因树脂ZH-1上残留有未反应完全的氯甲基,于是对树脂ZH-1进行二次交联反应,得到树脂ZH-2,树脂ZH-2的比表面积提高到753.28 m2/g,平均孔径为1.680nm.研究了树脂ZH-1和ZH-2对水溶液中苯酚的吸附性能.结果表明,树脂ZH-1和ZH-2对苯酚的吸附量都好于相同条件下的XAD-4,树脂ZH-2的吸附量是ZH-1的1.7倍,比表面积变大是吸附量变大的主要原因.Two kinds of polar adsorption resins ZH-1 and ZH-2 were prepared with phenetole,acetanilid and chloromethyl methyl ether. The structure of the resins were characterized. The BET surface areas of ZH-1 is 114.72 m2/g ,and the average pore size of ZH-1 is 1.682 nm. Unreacted chloromethyl group on resin ZH-1 was utilized to further cross-linking,The surface area of resin ZH-2 is up to 753.28 m2/g,and the average pore size of ZH-2 is 1.680 nm. Adsorptive behaviors of phenol from aqueous solution onto resin ZH-1 and ZH-2 were researched. Analysis results show that ZH-1 and ZH-2 have obvious effect on adsorption of phenol than that of XAD-4,and the adsorption capacity of ZH-2 for phenol is about 1.7 times as high as that of ZH-1 under the same conditions. Equilibrium adsorption capacity increases with the increasing of the surface areas.
