“…3, ranged from 60 to 140%. These results were comparable with those reported by other researchers (Cathum and Sabik, 2001;Cai et al, 2003;Hoai et al, 2003;Gatidou et al, 2007;Dirtu et al, 2008). The obtained recovery results were considered to be satisfactory, considering that different types of analytes with different chemical structure and polarities were extracted simultaneously.…”

“…From the results in Table 1, BSTFA yielded a fast derivatization reaction as the reaction was complete within 20 min, but this was obtained at a higher temperature (65°C) (Gatidou et al, 2007). Another study by Fiedler et al (2007) also used BSTFA but the reaction took place at room temperature for 2 h. These 2 studies indicated the effect of temperature on derivatization with BSTFA as the derivatization was quicker at an elevated temperature than at room temperature.…”

An improved derivatization protocol for the simultaneous determination of alkylphenol ethoxylates and brominated flame retardants with heptafluorobutyric anhydride under triethylamine amine base was investigated. The derivatization reaction was completed in 30 min at 50°C using hexane as solvent. Under these conditions, it was observed that alkylphenol ethoxylates and tetrabromobisphenol A were derivatized successfully in the presence of hexabromocyclododecane, lower congeners of polybrominated biphenyls and polybrominated diphenyl ethers. The improved protocol was applied to recovery of analytes of interest from simulated water samples after solid phase extraction. The recoveries achieved were above 60%. The limit of detection and limit of quantification ranged from 0.01-0.20 µg/ℓ and 0.05-0.66 µg/ℓ, respectively.

BACKGROUND:This study was carried out to establish an efficient sample preparation for the simultaneous determination of bisphenols (BPs) in river water samples using gas chromatography-mass spectrometry (GC-MS). Sample preparation was examined with conventional extraction methods, such as solid-phase extraction (SPE) and liquid-liquid extraction (LLE), and their efficiency was compared with validation results, including linearity of calibration curve, method detection limit (MDL), limit of quantification (LOQ), accuracy, and precision. METHODS AND RESULTS:The BPs (bisphenol A, BPA; bisphenol B, BPB; bisphenol C, BPC; bisphenol E, BPE; bisphenol F, BPF; bisphenol S, BPS) were analyzed using GC-MS. The range of MDLs by SPE and LLE methods was

“…A number of analytical methods such as high-performance liquid chromatography (HPLC), 3 liquid chromatography coupled with mass spectrometry (LC-MS), 4 gas chromatography− mass spectrometry (GC-MS), 5 fluorescence detection method, 6 flow injection inhibitory chemiluminescence method, 7 and enzyme-linked immunosorbent assay 8 have been reported for the detection of BPA. These methods are quite sensitive, but they are very complicated and require sophisticated instruments.…”

A highly sensitive electrochemical detection method for bisphenol A (BPA) has been developed by using multi-walled carbon nanotube (CNT)-doped titania-Nafion composite modified glassy carbon (GC) electrode. The CNT−titania−Nafion/GC electrode exhibited excellent electrocatalytic activity towards BPA. Therefore, the CNT−titania−Nafion/GC electrode showed improved voltammetric responses for BPA compared to that obtained with bare GC electrode. In addition, cetyltrimethylammonium bromide (CTAB), a cationic surfactant, was added into the BPA sample solution in order to accumulate BPA through hydrophobic interaction between CTAB and BPA. The CNT−titania−Nafion/GC electrode gave a linear response (r 2 = 0.999) for BPA from 1.0 × 10 −8 M to 5.0 × 10 −6 M with a detection limit of 9.0 × 10 −10 M (S/N = 3). The modified electrode showed good selectivity against interfering species and also exhibited good reproducibility. The present electrochemical sensor based on the CNT-titania-Nafion/GC electrode was applied to the determination of BPA in food package samples.
