摘要:环境内分干扰物(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,近年来人们开晨了模拟脂肪
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沙千扰物的研究。仿生吸附剂主要有两类:聚羟基丁
酸酯类和乙酸纤维素一三油酸甘油酯类。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

Abstract: The negative effects of endocrine disrupting chemicals(EDC)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
Key words: endocrine disrupting chemicals(EDCS ); environmental friendly bionic adsorbent
