| 摘 要： | 以亲水性小分子有机酸没食子酸作为研究对象,研究了氨基修饰超高交联树脂对没食子酸的吸附行为和机理.结果表明,氨基修饰超高交联树脂WJN-10对没食子酸有较高的吸附容量和吸附作用力;π-π共轭作用是树脂WJN-10吸附没食子酸主要作用力;WJN-10吸附没食子酸是物理吸附主导;吸附速率主要受控于颗粒内扩散过程;WJN-10对没食子酸有较好的吸附-脱附性能.

| Abstract: | As typical natural organic acid of hydrophilicity and small molecule,gallic acid(GA) serves to study the adsorption act and mechanism on a new hyper cross-linked resin modified by amino function groups. The adsorption isotherm data indicates that WJN-10 show higher adsorption force and amounts of gallic acid than that of other adsorbents. Its Absorption was characterized by physical Absorption. Batch kinetic studies indicate that the adsorption of GA on WJN-10 could only be fitted by intra-particle diffusio... |
