| 摘 要： | 利用电导技术研究D252大孔离子交换树脂吸附低浓度游离酸的行为。实验结果表明：随着吸附质浓度的增大．表观吸附速率常数K逐渐减小；吸附质与吸附剂之间的相互作用能逐渐减小；吸附质对吸附剂的亲和能也逐渐减小。

| Abstract: | The adsorption of low concentration free acid on macroporous strong basic D252 resin was studied by conductivity method.The results show that the apparent adsorption rate(k),the interaction energy between the absorbent and the absorbate and the affinity of the absorbate to the absorbent all reduce gradually with the increase of acid concentration. |

| Keywords: | conductivity method D_(252) resin adsorption free acid. |
