电化法研究壳聚糖树脂与游离酸的相互作用

利用电化实验技术，跟踪观察交联壳聚糖树脂吸附低浓度游离酸的行为，讨论了酸和甲醇浓度等因素对吸附的影响，利用固-液相互作用方程，求取吸附剂一吸附质相互作用能。实验结果表明，交联壳聚糖树脂吸附低浓度游离酸的过程是遵循单分子层机制进行的，表观吸附速率常数随着吸附质浓度和外加甲醇含量的增大而减小，表观吸附速率常数与吸附剂一吸附质相互作用能（U）存在线性相关。

ELECTROCHEMICAL PROCESS APPLIED TO THE STUDY OF INTERACTION BETWEEN CROSSLINKED CHITOSAN RESIN AND FREE ACID

The adsorption of low concentration free acid by crosslinked chitosan resin was followed by electrochemical process measurement. The effect of acid concentrationand the presence of foreign CH3OH on adsorption was discussed. The interaction energy between the adsorbent and the adsorbate was obtained by the solid-Liquid interaction equation. Experimental results show that the low concentration of free acid attracted by crosslinked chitosan resin obeys the formation of monolayer sorption.The apparent sorption rate constant decrease with an increase in solution concentration of adsorbate and foreign CHaOH. There is a linear relationship between the apparent sorption rate constant and adsorbent - adsorbate interaction energy.
