中文摘要：

邻苯二甲酸二丁酯（DBP）是水源水中常见的内分泌干扰物。以新型的饮用水处理材料离子交换树脂（MIEX）为吸附剂,以DBP为目标污染物,从动力学、吸附等温线、电荷密度测定、红外光谱表征、X射线光电子能谱以及共存组分影响等方面分析了MIEX去除DBP的效果和机理。MIEX去除DBP的过程仅需20 min即达到平衡,可用准二级动力学描述,中性溶液中DBP的饱和吸附量为0.944 mg·g^-1。中性条件下DBP带电量仅为2.7×10^-3mmol·mmol^-1,MIEX与DBP间的作用并非离子交换,而是以DBP分子与MIEX基材间的疏水作用以及氢键作用为主。高浓度SO4^2-和Cl^--不会对DBP的去除效果产生影响;高浓度的腐殖酸（HA）轻微抑制DBP的去除,但微量DBP并不会影响MIEX对HA的去除效果。因此,MIEX作为能高效去除水中天然有机物的新型材料,也可用于去除其中微量的DBP,适用于饮用水复合污染的处理。

英文摘要：

Di-n-butyl phthalate（DBP） is one of endocrine disrupting chemicals（EDCs）, which is commonly found in aquatic environment. In this study, DBP removal by magnetic ion exchange resin（MIEX） was investigated with respect to kinetics, isotherms, charge density analysis, Fourier transform infrared spectroscopy（FT-IR） analysis, X-ray photoelectron spectroscopy（XPS） as well as the effect of accompanying components. The removal of DBP was stable after 20 min, and pseudo-second kinetic model could well depict the removal process. In neutral p H soultion, the maxium uptake capacity of DBP by MIEX was around 0.944 mg·g^-1. Since the charge density of DBP was only 2.7×10^-3 mmol·mmol^-1 at neutral p H, the removal of DBP by MIEX was mainly based on the hydrophobic interaction and hydrogen bonding between MIEX matrix and DBP, instead of ion exchange. High concentrations of accompanying SO4^2- and Cl^-- did not affect the DBP removal. The presence of humic acid（HA） slightly decreased the DBP removal; however, the HA removal by MIEX was not affected at all. As an emerging novel technology for the removal of natural organic matters, MIEX can also remove DBP from aqueous solution. Therefore, it can be applied for drinking water treatment when surface water with complex micropollutants was used as the source.
