In the present study, a flexible, high-strength composite consisting of graphene oxide sheets and aramid nanofibers (GO/ANF) was made and used as a novel sorbent for thin film microextraction. The resulting composite consists of oriented graphene layers separated by randomly dispersed ANFs, interconnected by hydrogen bonding and ??? interactions between the materials. The GO/ANF composite film was utilized for the pre-concentration and determination of methyl-, ethyl-, propyl-, and butylparaben in water samples (i.e., swimming pool water, river water, and wastewater). High-performance liquid chromatography with UV-detection used for the detection. The TFME conditions were optimized by studying the parameters such as the desorption solvent type, desorption volume, desorption time, ionic strength of the sample, and extraction time. The optimal conditions for the method were as follow extraction time of 30 min, acetonitrile as desorption volume, desorption solvent volume of 150 µL, and extraction time of 5 min. Also, the results indicated that the ionic strength of the sample had no significant effect on extraction efficiency. The limits of detection under the optimal conditions were 0.44-0.81 µg/L. The method exhibited linearity in the range of 1-200 µg/L, with the limit of quantification of 1.5-2.7 µg/L. The determination coefficients were higher than 0.9971. The intra- and inter-assay precision (RSD%, n = 3) were in the range of 3.6-7.7% and 5.0-17%, respectively. The relative recovery values for the spiked samples were in the range 38.6-99.3%. The application of the present methodology to monitor trace levels of parabens in water samples, showed that the method was easy to work-up, efficient and environmentally friendly, providing remarkable sensitivity, performance, as well as excellent robustness and analytical reproducibility.
