摘要
通过静态、动态吸附实验，得出Ｈ１０３树脂吸附水溶液中邻硝基苯酚的总传质系数大于Ｈ１０３树脂吸附水溶液中对硝基苯酚的总传质系数，吸附过程均为优惠吸附，吸附等温线可用Ｌａｎｇｍｕｉｒ或Ｆｒｕｎｄｌｉｃｈ公式表示，符合ＧｉｌｅｓＬ１型。吸附速度可用Ａｂ＝ａｅｂ／τ表示。
A dynamic adsorption model of fixed bed adsorber with resin H103 as the adsorbent for treating aqueous solution containning p nitrophenol and o nitrophenol. By fitting the experimental data, the adsorbing rate equation can be expressed as A b =ae b/τ , and the differential adsorption heat equation as q d=a 1+a 2A b+a 3A 2 b-Rt. The adsorption isotherms can be described by Fredundlich and/or Langmuir equation.
