建立了一种基于温度敏感聚合物诱导相分离的新型分散液液微萃取方法，用于测定苯酚、2,4-二氯苯酚（2,4- dcp）、β-萘酚和双酚A。研究了β-环糊精-聚n-异丙基丙烯酰胺与2,4- dcp的相互作用。结果表明，2,4- dcp与具有螺旋结构和球状结构的聚合物之间存在相互作用。对影响酚类物质提取的参数进行峰面积优化。在最佳条件下，相关系数为0.9828 ~ 0.9990。所有分析物的检出限为0.01 ~ 1.0 μ L−1，定量限为0.04 ~ 3.50 μ L−1。将所建立的方法成功地应用于三个护城河样本的分析。相对加样回收率为81.3 ~ 117.3%，相对标准偏差小于17%。
A novel dispersive liquid-liquid microextraction method based on temperature-sensitive polymer-induced phase separation was assessed for the determination of phenol, 2,4-dichlorophenol (2,4-DCP), β-naphthol, and bisphenol A. The interaction between β-cyclodextrin-poly (N-isopropylacrylamide) and 2,4-DCP was investigated. The results showed that there was an interaction between 2,4-DCP and the polymer with coiled structures and globular structures. The parameters that affected the extraction of phenols were optimized for the peak area. Under optimal conditions, the correlation coefficients were in the range of 0.9828-0.9990. The limits of detection for all the analytes varied from 0.01 to 1.0 μg L−1, and the limits of quantification were between 0.04 and 3.50 μg L−1. The established method was applied successfully to analyze three moat river samples. The relative recoveries were between 81.3 and 117.3%, and the relative standard deviations were less than 17%.
