We report on the fabrication of a thin-film composite for the extraction of bisphenol A from aqueous solutions. Nylon-6, C18 particles, and polyethylene glycol were used to prepare the thin film sorbent. Bisphenol A was used as a model compound to evaluate the extraction efficiency of the sorbent. High-performance liquid chromatography with UV detection was used for the analysis. The extraction yield of the sorbent was compared with other thin films fabricated using different sorbents including nanoclay, LiChrolut EN, and multiwalled carbon nanotubes. Experimental parameters affecting the extraction performance (extraction time, desorption condition, sample stirring, and ionic strength of the sample solution) were investigated. The detection limit and the dynamic range of the method were 0.05 and 0.15-50 μg/L, respectively. The relative standard deviation of the method at two concentration levels (0.5 and 20 μg/L) was less than 7.2%. Finally, a polycarbonate baby bottle, river water, and wastewater samples were analyzed by the method.
我们报道了一种用于从水溶液中萃取双酚A的复合薄膜的制备。使用尼龙-6、C18颗粒和聚乙二醇制备薄膜吸附剂。以双酚A作为模型化合物来评估吸附剂的萃取效率。采用配有紫外检测的高效液相色谱进行分析。将该吸附剂的萃取产率与使用包括纳米黏土、LiChrolut EN和多壁碳纳米管等不同吸附剂制备的其他薄膜进行了比较。研究了影响萃取性能的实验参数（萃取时间、解吸条件、样品搅拌以及样品溶液的离子强度）。该方法的检测限和动态范围分别为0.05和0.15 - 50μg/L。该方法在两个浓度水平（0.5和20μg/L）下的相对标准偏差小于7.2%。最后，采用该方法对聚碳酸酯奶瓶、河水和废水样品进行了分析。
