| 摘 要： | 用丙烯酸系树脂XAD-7和超高交联树脂NDA-150对5-磺基水杨酸进行了吸附研究。结果表明，在无甲醇的水溶液中，超高交联树脂NDA-150对5-磺基水杨酸有明显的吸附优势，其吸附量大于丙烯酸系树脂XAD-7；在有甲醇存在的溶液中，超高交联树脂NDA-150的吸附能力明显下降，而丙烯酸系树脂XAD-7的吸附能力却几乎不受甲醇的影响。范德华力是超高交联树脂NDA-150在吸附过程中的主要作用力，而氢键是丙烯酸系树脂XAD-7在吸附过程中的主要作用力。

| Abstract: | The adsorption research of 5-Sulfosalicylic acid is carried out by acrylic ester resins XAD-7 and highly cross-linked resins NDA-150.The results show that the adsorption capacity of highly cross-linked resins NDA-150 is superior to that of acrylic ester resins XAD-7 in the solution without methanol.But in the solution with methanol,the adsorption capacity of NDA-150 decreases obviously,while methanol has little effect on adsorption capacity of XDA-7.One reason to explain the phenomena is that the Van der waals force is main working force in adsorption of resins NDA-150,and hydrogen bonding is main working force in adsorption of XAD-7. |
