摘　　要： 目的:在线跟踪树脂吸附低浓度游离酸的行为,研究乙醇、氯化钠等外界环境对吸附的影响,优化生产工艺。方法:利用电导实验技术、固-液相互作用方程,求取吸附剂-吸附质相互作用能。结果:树脂吸附游离酸,其表观吸附速率常数随着乙醇、氯化钠浓度的增大而减小。结论:表观吸附速率常数与吸附剂-吸附质相互作用能呈线性相关。 Objective：The adsorption of low concentration of free acid by resin online was tracked by electric conductance method.The effect of the concentration of C2H5OH and NaCl on adsorption was studied and the production process was optimized.Methods：The interaction energy between the adsorbent and the adsorbate was obtained by the interaction equation of the solid-liquid.Results：The apparent adsorption rate decreased with the increase in the concentration of C2H5OH and NaCl.Conclusion：There was a linear interactionship between the apparent adsorption rate constant and adsorbent-adsorbate interaction energy.
