“…41,42 However, a large number of studies showed that BPA has strong biological toxicity and can interfere with hormonal activities. 43,44 For BPA detection, many traditional methods such as high-performance liquid chromatography (HPLC), uorimetry, chemiluminescence, gas chromatography-mass spectrometry (GC-MS), and enzyme-linked immunosorbent assay (ELISA) [45][46][47][48][49] have been developed. Electrochemical detection has its unique advantages such as cheap instrument, low cost, fast detection and high sensitivity.…”

“…Moreover, some investigations pointed out that people with excess BPA in their bodies are more likely to cause heart disease, diabetes, and liver damage [6]. Therefore, the amount of BPA is required to be less than 0.05 mg kg −1 based on Chinese Health Standard (GB 13116-91) [7].…”

Three-dimensional gold nanodendrites with (111)-oriented growth were fabricated on a glassy carbon electrode by one-step electrodeposition of AuCl 4 − in the presence of Lasparagine. The gold nanodendrites were functionalized with 4-mercaptobenzoic acid (4-MBA), which showed the improved catalytic performance for sensitive and selective determination of bisphenol A (BPA) by differential pulse voltammetry. The oxidation peak currents of BPA at 514 mV showed linear responses to BPA concentrations from 0.05 to 55.0 μM (R 2 =0.995), with the detection limit of 1.2 nM (S/N=3). The modified electrode was extended for trace detection of BPA in (spiked) real samples with satisfied results.

“…The most widely used methodologies for the determination of trace levels of phenol compounds is solid phase extraction followed by gas chromatography (GC) after derivatization [3,10]. Alternatively, solid phase microextraction (SPME) and stir bar sorptive extraction (SBSE) with in-situ derivatization followed by GC coupled to mass spectrometry (GC-MS) analysis, or LC-MS without the derivatization step had also been proposed to monitor the class of compounds [4,11,12,13,14,15]. Recently, our group has introduced a novel static microextraction technique, bar adsorptive microextraction (BAμE), that uses nanostructured materials, and have demonstrated it to be a remarkable alternative for trace analysis of medium-polarity to polar compounds in aqueous media [16,17].…”

Bar adsorptive microextraction combined with liquid desorption followed by high performance liquid chromatography with diode array detection (BAµE-LD/HPLC-DAD) is proposed for the determination of trace levels of five phenol compounds (3-nitrophenol, 4-nitrophenol, bisphenol-A, 4-n-octylphenol and 4-n-nonylphenol) in surface water matrices. By using a polystyrene-divinylbenzene copolymer (PS-DVB) sorbent phase, high selectivity and efficiency is achieved even against polydimethylsiloxane through stir bar sorptive extraction. Assays performed by BAµE(PS-DVB)-LD/HPLC-DAD on 25 mL water samples spiked at the 10.0 µg/L levels yielded recoveries over 88.0% ± 5.7% for all five analytes, under optimized experimental conditions. The analytical performance showed good precision (RSD < 15%), detection limits of 0.25 µg/L and linear dynamic ranges (1.0-25.0 μg/L) with determination coefficient higher than 0.9904. By using the standard addition method, the application of the present method to surface water matrices allowed very good performances at the trace level. The proposed methodology proved to be a suitable alternative to monitor phenol compounds in surface water matrices, showing to be easy to implement, reliable, sensitive and requiring a low sample volume.
