摘　　要：利用电位技术法,在线研究D354树脂对邻苯二甲酸氢钾的吸附行为,利用固-液界面吸附动力学方程,分别求出固-液吸附表观速率常数(k)、相互作用能(U)以及相作用势(E),用以表征吸附剂对吸附质的吸附能力。Adsorption behavior of Potassium hydrogen phthalate on D354 resins at different low concentration was followed by using electric potential method. The rate constant of apparent adsorption and the interaction energy between the adsorbent and the adsorbate were evaluated by the kinetic equation of solid-liquid interface adsorption. The adsorption potential E can be estimated according to Polanyi equation, which all token the ability of adsorption between the adsorbent and the adsorbate.
