| 摘 要： | 研究了带有不同功能基团的超高交联吸附树脂NG-10和NJ-99对水溶液中芳香两性化合物氨基苯甲酸的静态吸附性能,并与不带功能基团的吸附树脂CHA-111和XAD-4进行了比较.研究结果表明,树脂NJ-99对水溶液中氨基苯甲酸的吸附能力高于其他树脂.邻氨基苯甲酸在4种树脂上的吸附量均大于对氨基苯甲酸,主要原因是其溶解度小.吸附等温线采用经验的Freundlich方程和理论的Langmuir吸附方程来拟合,在实验所研究的浓度范围内,方程的拟合相关性均很好.

| Abstract: | The performance of static adsorption of aromatic amphoteric compound aminobenzoic acid onto the multifunctional polymeric adsorbents NJ-99 and NG-10 was investigated in details and some comparison was made between NJ-99,NG-10,the common adsorbent CHA-111 and XAD-4.The results showed that the adsorption capacities of NJ-99 were highest,which may be contributed to the hydrogen-bonding interaction between the amino groups of the adsorbent and the carboxyl groups of aminobenzoic acid and the unusual pore distribution.The capacities of all the adsorbents to o-aminobenzoic acid were higher than p-aminobenzoic acid,which is owing to the lower solubility of o-aminobenzoic acid.The equilibrium data were well correlated with Langmuir and Freundlich adsorption isotherm equations. |
