Abstract: The negative effects of endocrine disrupting chemicals(EDCs)to human health and environment are concerned by the whole society. This issue has been a hotspot in the field of environmental governance research. Considering the high octanol-water partition coefficient and bioaccumulation of the pollutants,the fat cell was mimiced to prepare a bionic adsorbent to remove EDCs in water recently. There are two main kinds of bionic adsorbents,poly-3-hydroxybutyrate(PHB)and triolein embedded into cellulose acetate(CA). Both of them can be used to remove the low concentration EDCs from water quickly and efficiently. Modified biomimetic fat cess (MBFC) and CA-triolein can be regenerated at least for five times,without significant decreasing of removal efficiency. This review is conducted on the adsorptive characteristics and adsorption mechanism of this kind of absorbents,and an outlook for the future research on removal of EDCs was also included.

摘要: 环境内分泌干扰物(EDCs)对人类健康和生态环境的危害受到全社会的关注,已成为环境治理研究的热点和难点。由于这类污染物具有较高的辛醇-水分配系数、易于生物富集的特点,近年来人们开展了模拟脂肪细胞的生物富集性制备仿生吸附剂处理水体中的环境内分泌干扰物的研究。仿生吸附剂主要有两类:聚羟基丁酸酯类和乙酸纤维素-三油酸甘油酯类。这两类吸附剂都能高效、快速地去除水中低浓度的环境内分泌干扰物。改性网状仿生脂肪吸附剂和球形乙酸纤维素-三油酸甘油酯吸附剂可再生使用至少5次,吸附效果并未见明显下降。本文综述了这类仿生吸附剂的吸附特性和吸附机理,并展望了今后的研究热点。
