摘要
利用电导实验技术 ,跟踪观察弱酸性树脂吸附低浓度游离碱的行为 ,研究温度对吸附的影响 ,测定吸附活化能 ( Ea)和吸附剂 -吸附质相互作用能 ( U)。实验结果表明 ,温度升高 ,吸附剂 -吸附质相互作用能增加 ,表观吸附速率常数 ( k)增大 ,而且 U与 T存在良好的线性相关 ( r=0 .995 1 )
The behavior of adsorption of low concentration free base by weak acidic resin was followed by conductivity technique. The effect of temperature on adsorption was studied, adsorbed activation energy (E a) and interaction energy of adsorbent adsorbate (U) were determined. Experiment results indicated that the interaction energy of adsorbent adsorbate and the apparent adsorption rate constant (k) were increased when the temperature was going up. There was a good linear relation between U and T (r= 0.9951) .
