| 摘 要： | 考察了两种不同表面化学性质粉末活性炭（WP及其改性炭WPN）对松花江原水和砂滤水中六种加标酚类内分泌干扰物的去除情况。试验结果表明，活性炭对六种目标物的吸附能力与其憎水性（logKOW）有关，依次为：4-n—NP〉E1〉DES〉EE2〉E2〉BPA；活性炭吸附降低了水中的TOC与UV254值，同时也去除了水中大部分的内分泌干扰物，WP和WPN两种活性炭对江水和砂滤水中六种目标物的去除率分别为26．82％～85．97％和74．62％～96．64％，其中WPN的吸附效果相对较好。试验结果还表明，活性炭对酚类内分泌干扰物的吸附能力受水中有机物与活性炭物化性质的影响较大，通过一定的改性处理获得孔结构与表面化学性质均有利于去除水中有机污染物的活性炭，并将其用于给水的深度处理，对于提高活性炭的吸附能力、使用寿命及确保出水水质安全都具有重要意义。

| Abstract: | Removal of six phenolic endocrine disrupting chemicals from Songhua River water and sand-filtered water by adsorption on two powdered activated carbons (WP and WPN) was investigated,where the surface chemical properties of adsorbents were different. The results indicate the adsorption capacities for various targets on powdered activated carbons have a relation to their hydrophobic properties (logKOW),and the sequence is 4-n-NP>E1>DES>EE2>E2>BPA. Furthermore,the values of TOC and UV254 are decreased by activ... |
