[目的]研究水溶液中啶虫脒和苯胺双组分在树脂上的吸附行为、树脂对2组分的吸附选择性。[方法]以啶虫脒/苯胺为吸附质,以D201和ZH202树脂为吸附剂,研究啶虫脒和苯胺在单组分、双组分水溶液中2种树脂上288、303、313 K温度下的吸附行为。[结果]2种吸附剂对单组分2种吸附质的吸附等温线符合Freundlich方程,苯胺和啶虫脒在2种吸附剂上吸附过程均为放热过程。[结论]啶虫脒和苯胺双组分共存吸附体系下,呈现竞争吸附现象。
[Objective] The research aimed to study the adsorption behavior of the two components of acetamiprid and aniline in the aqueous solution and the adsorption selectivity of the resin to the two components. [Method] With acetamiprid / aniline as adsorbate and D201 and ZH202 resin as adsorbents, the effects of acetamiprid and aniline on the two kinds of resins at single, two component aqueous solution at 288,303,313 K The adsorption behavior. [Result] The adsorption isotherms of two adsorbents for one component and two adsorbents were in accordance with the Freundlich equation. The adsorption of aniline and acetamiprid on the two adsorbents was exothermic. [Conclusion] Acetamiprid and aniline bicomponent coexistence adsorption system, showing a competitive adsorption phenomenon.
