In this work, a simple and versatile ultrasound-assisted extraction (UAE) procedure, which provides high separation efficiency for bisphenol A (BPA), was developed for its indirect determination in beverages in contact with plastic containers by flame atomic absorption spectrometry (FAAS). The method is based on charge transfer reaction, in which BPA reacts with Cu(II) in alkaline tartrate solutions of pH 8.0 to produce Cu(I), which reacts with ion-pairing reagent, Promethazine, being a phenothiazine derivative (PMZ), in the presence of cetyl trimethylammonium bromide (CTAB). For the indirect determination of BPA using FAAS, the change in signal of Cu(II) depending on BPA concentration was investigated in detail. At optimal conditions, the analytical features of the method were obtained as follows; linearity ranges of 1.5-100 µg L-1 for direct aqueous calibration solutions and 3-125 µg L-1 for matrix matched calibration solutions; the limits of detection and quantification of 0.47 and 1.56 µg L-1 ; sensitivity enhancement and pre-concentration factors of 135 and 150, respectively. The method accuracy was validated by repeatability/reproducibility precision studies using standard addition method. As the last, the method was successfully applied for determination of BPA in selected samples. BPA as a food stimulant was detected in ranges of 2.70-3.80 µg L-1 in waters and 3.10-5.40 µg L-1 in milk products while its levels changed in ranges of 6.40-7.70 and 4.30-19.2 µg L-1 in beverages with and without alcohol. These levels were highly lower than the specific migration limit set by European Union.

“…To monitor the environmental levels, behaviors and fate of BPA, many methods, such as capillary electrophoresis [ 11 ], gas chromatography coupled with mass spectrometry (GC-MS) [ 12 ], high performance liquid chromatography mass spectrometry (HPLC-MS) [ 13 ], enzyme linked immune sorbent assay (ELISA) [ 14 ], electrochemical methods [ 15 , 16 ], etc., have been developed. Combined with pretreatment procedures of solid-phase extraction [ 17 ], liquid-liquid extraction [ 18 ] and immunoaffinity chromatography [ 19 ], GC-MS, HPLC-MS and ELISA can be used for selectively and sensitively determining BPA in complex matrices [ 20 , 21 ].…”

Due to the endocrine disturbing effects of bisphenol A (BPA) on organisms, rapid detection has become one of the most important techniques for monitoring its levels in the aqueous solutions associated with plastics and human beings. In this paper, a glassy carbon electrode (GCE) modified with molybdenum selenide/reduced graphene oxide (MoSe2/rGO) was fabricated for in situ determination of bisphenol A in several beverages. The surface area of the electrode dramatically increases due to the existence of ultra-thin nanosheets in a flower-like structure of MoSe2. Adding phosphotungstic acid in the electrolyte can significantly enhance the repeatability (RSD = 0.4%) and reproducibility (RSD = 2.2%) of the electrode. Under the optimized condition (pH = 6.5), the linear range of BPA was from 0.1 μM–100 μM and the detection limit was 0.015 μM (S/N = 3). When using the as-prepared electrode for analyzing BPA in beverage samples without any pretreatments, the recoveries ranged from 98–107%, and the concentrations were from below the detection limit to 1.7 μM, indicating its potential prospect for routine analysis of BPA.

“…For monitoring the pollution levels and ecological risks of BPA, many methods based on capillary electrophoresis [9][10][11], gas chromatography coupled with mass spectrometry (GC-MS) [12][13][14][15], high performance liquid chromatography mass spectrometry (LC-MS) [16,17], enzyme linked immune sorbent assay (ELISA) [18][19][20], and electrochemical methods [21][22][23][24] have been developed. Pretreatment procedures, such as solid-phase extraction [24][25][26], liquid-liquid extraction [27,28], and immunoaffinity chromatography [29,30], are often involved when using GC-MS, HPLC-MS, and ELISA for analyzing BPA in complex matrices [31,32].…”

Determination of Bisphenol A in Beverages by an Electrochemical Sensor Based on Rh2O3/Reduced Graphene Oxide Composites

A novel electrochemical sensor, based on a Rh2O3–reduced graphene oxide (rGO) composite modified carbon electrode, has been developed for detecting bisphenol A (BPA) in beverages. The prepared Rh2O3/rGO and its precursor materials were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). Under optimum conditions, the sensor presented good electrochemical performance for analyzing BPA, with a linear range of 0.6–40 μM, detection limit of 0.12 μM, good reproducibility, and excellent stability. The good performance can be attributed to the combination of the good catalytic properties of Rh2O3 and good conductivity of rGO. The sensor is directly used for detecting BPA in the residual solutions of four beverages after simple filtration, with satisfactory recoveries of 93–99%.
