摘　　要：利用电导实验技术 ,跟踪观察两性离子交换树脂吸附低浓度游离酸的行为。实验结果表明 ,两性树脂吸附低浓度游离酸时 ,表观吸附速率常数随吸附质浓度的增大而降低 ,吸附过程是遵循单分子层机制的行为。The adsorption behavior of free acid on amphoteric resin was followed by electric conductance technique. The effect of acid concentration and temperature on adsorption was discussed. Experimental results show that the low concentration of free acid attracted by amphoteric resin obeys the formation of monolayer adsorption ,the apparent adsorption rate constant decreases with an increase in adsorbate concentration.
