酞酸酯及其降解产物的前处理技术研究综述

Review in Pre-treatment Technology of Phthalate Ester and Their Degradation Products

酞酸酯是一类普遍使用的有机化合物,主要用作塑料的增塑剂,目前在环境中已经大量存在,由于其具有致癌、致畸和致突变性,引起广泛的关注。综述了近年来环境中酞酸酯类及其降解产物前处理技术的研究进展,指出现阶段主要有液-液萃取(LLE)、固相萃取(SPE)、固相微萃取(SPME)、固相膜萃取(SME)、液相微萃取技术(LPME)、超临界萃取(SFE)和衍生化技术等7种酞酸酯前处理方法;介绍了酞酸酯及降解产物衍生化技术的应用研究,并提出了前处理技术应用的研究前景。

As one type of common used organic substances,phthalate Acid esters（PAEs） can be found in environment.PAEs are mainly used as plasticizers for polyvinyl chloride in a wide range of domestic and industrial applications.PAEs have been paid more attention to its teratogenicity,mutagenicity and carcinogenicity.The authors reviewed the research progress of the pre-treatment technologies of phthalate esters and its degradation products in the environment,pointed out 7 phthalates Technology pretreatment that are liquid-liquid extraction（LLE）,solid phase extraction（SPE）,solid phase micro extraction（SPME）,solid Phase Extraction（SME）,liquid phase microextraction（LPME）,supercritical fluid extraction（SFE） and derivatization technique,introduced the application research of the derivative technology of phthalate esters and its degradation products,and made a research prospects of the technology.
