摘    要:研究了水源水和生化尾水中的代表性模拟背景污染物单宁酸和代表性有机毒物苯酚之间的竞争吸附行为,开展了单组分、同时竞争吸附和预负载竞争吸附实验.研究表明,单宁酸对苯酚在复合功能树脂上的吸附有显著削弱作用.竞争吸附机理包括孔堵塞和吸附质间作用:单宁酸对树脂上微孔的堵塞,减少了苯酚优势吸附位点的数量,降低了吸附剂表面的异质性;吸附质间作用削弱了树脂对苯酚的吸附作用力.

关 键 词:单宁酸  苯酚  复合功能树脂  孔堵塞机理  吸附质间作用

Abstract:Tannic acid, a representative background compound of source water and biologically treated sewage effluent, was chosen to study the competitive effect on the adsorption of phenol by a bi-functional polymeric adsorbent.Single solute adsorption, simultaneous adsorption and preloading experiments were performed.The result indicated that tannic acid had a dramatic effect on phenol adsorption onto resin through different mechanisms, including interactions between adsorbates and pore blockage.The interaction betw...
Keywords:tannic acid  phenol  bi-function resin  competitive adsorption  pore blockage  interaction between adsorbates
