中文摘要：

根据腐殖酸的结构特点选取适当模型物,采取紫外-可见分光技术研究瓜环的投加量、时间、温度及pH值对腐殖酸模型物去除的规律。研究表明,模型物的结构是影响瓜环对腐殖酸模型物去除的最主要因素,其中羧基和芳环是影响瓜环对模型物吸附效果的主要基团;瓜环对腐殖酸及其模型物的吸附主要为物理吸附,并且吸附有较宽的pH值范围;瓜环对腐殖酸模型物去除作用的较优条件为瓜环投加量1.8g/L,初始浓度20mg/L,平衡时间5h。在此条件下,瓜环对腐殖酸模型物苯甲酸、2-萘酚、萘、苯甲醚及腐殖酸的去除率分别为94.52%、98.24%、81.52%、85.66%和99.85%。

英文摘要：

Removal law of model compounds based on the structural characteristics of humic acid （HA） in wastewater by cucurbiturils was explored by ultraviolet spectrum under the different conditions such as the ad- sorbent dosage,contact time,temperature and pH value. The structure of model compounds was the most fac- tors for the removal rate of HA by cucurbiturils and carboxyl groups and the aromatic ring in HA played a deci- sive role for removal efficiency~ the interaction of cucurbiturils and model compounds mainly were physical effects, the adsorption had a wide range of pHi in the appropriate experimental conditions, the maximum re- moval rate of benzoic acid, 2-naphthol, naphthalene, benzyl alcohol and HA were 94.52% ,98.24% ,81. 52%, 85.66% and 99.85% when adsorbent dose, the amount of initial adsorbent and equilibrium time were 1.8g/L, 20mg/L and 5h.
