  • 摘要: 氯甲基聚苯乙烯中50%的-CH2Cl转化为-CH2-交联桥，50%的-CH2Cl与邻氨基嘧啶反应，制备邻氨基嘧啶负载的含超高交联树脂孔结构和大孔树脂孔结构的双重孔结构树脂（命名为CY-01树脂），对比研究CY-01树脂和H-103树脂对水杨酸的吸附性能和吸附机理.实验表明两种树脂对水杨酸的吸附量顺序为CY-01>H-103.CY-01树脂在pH值2.76时对水杨酸的吸附量最大，H-103树脂对水杨酸的吸附量与水杨酸的分子比随pH值的变化相一致.两种树脂对水杨酸的吸附速率顺序为CY-01>H-103.由于CY-01树脂的双重孔结构特征，CY-01树脂比H-103树脂吸附水杨酸表现出了更大的吸附量和吸附速率.H-103树脂吸附水杨酸以疏水作用为吸附机理，CY-01树脂吸附水杨酸存在疏水作用和阴离子交换多重吸附机理.
    Abstract: 50% of -CH2Cl groups in chloromethylated polystyrene was transformed to -CH2-crosslinked bridge, while the residual 50% of -CH2Cl groups was reacted with o-aminopyrimidine. The o-aminopyrimidine supported resin with double pore structure of hypercrosslinked resin and macroporous resin (denoted CY-01) was prepared. The adsorption properties and mechanism to salicylic acid on CY-01 resin were investigated as compared with H-103 resin. The adsorption capacity to salicylic acid on the two resins followed the order CY-01 > H-103. The adsorption capacity to salicylic acid on CY-01 resin was the maximum at pH 2.76. The adsorption capacity to salicylic acid on H-103 resin was consistent with the proportion of salicylic acid molecular with pH value. The adsorption rate to salicylic acid on the two resins followed the order of CY-01 > H-103. The greater adsorption capacity and the greater adsorption rate of salicylic acid on CY-01 resin than those of H-103 resin were attributed to the double pore structure of CY-01 resin. The adsorption mechanism of salicylic acid on H-103 resin was the hydrophobic interaction, while the adsorption of salicylic acid on CY-01 resin was the multifunctional adsorption mechanism of the hydrophobic interaction and the anion exchange.
