烷基酚聚氧乙烯醚的环境危害及检测方法评价

Envioronmental Hazard of Alkylphenol Ethoxylates and Evaluation on its Analytical Methods

烷基酚聚氧乙烯醚(APEO)是目前应用广泛的一大类非离子型表面活性剂。APEO对环境具有毒性、难生物降解性,且生物降解代谢物对环境具有潜在的危害性。有关APEO尤其是痕量APEO的定性定量分析还处在研究阶段,各检测方法的重现性差,目前我国许多检测机构还无法检测,亦无相关的标准方法。本文结合作者工作全面评述了烷基酚聚氧乙烯醚的性质、用途、生物降解性及对环境的危害;总结了国内外的相关法规和现状;讨论了烷基酚聚氧乙烯醚的各种预处理方法和测定方法并指出了应用中存在的一些问题及其研究进展。

Alkylphenol ethoxylates（APEO） are a kind of non-ion surfactants used widely, which are potential hazardous to environment because of its toxicity, non-biodegradation and biodegradable products. The quality and quantity analytical methods for trace amounts of APEO are developed, of which some methods are of bad repeatability. At present, APEO are not detected by many laboratories, and there is no relative standard method. Combined with our research work, the character, usage, biodegradation of APEO and its hazard on environment were reviewed in this paper. The relevant laws and current situations in domestic and overseas were also concluded. Moreover, the different pretreatment and determination methods were discussed, and some problems for determination of APEO were pointed out.
