“…A comparison of the analytical performance of the developed method with reported on-line methods [ 17 , 18 , 19 , 20 , 25 , 26 ] is summarized in Table 4 . To the best of our knowledge, in addition to this study, there is one study which reported on-line pretreatment coupled with HPLC to determine multiple BPs in water matrix [ 17 ]. The remaining studies reported only one or two types of BPs.…”

“…In addition, the background contamination of bisphenol substances released from laboratory plastic products may also lead to significant errors, especially when detecting ultra-trace level of BPs [ 16 ]. Therefore, it has become a new research trend to explore an automatic on-line combination technology of sample pretreatment and detection [ 7 , 17 , 18 , 19 ]. The combination of on-line sample pretreatment and high-performance liquid chromatography can reduce the labor intensity of technicians, realize the high automation of the analysis process, and the solid phase extraction column can be recycled for several times, saving the analysis cost.…”

“…Up to now, there are few automatic on-line combinations of technology for sample pretreatment and detection available for simultaneously detecting a variety of BPs. Han has reported an online enrichment-HPLC-FLD method in simultaneous monitoring of bisphenols in children’s water bottles; however, manual syringe injection makes the entire analysis process not practically automated [ 17 ]. An on-line coupling of nanofibrous extraction with column-switching HPLC method has been established for the determination of bisphenol A in environmental water samples by Háková [ 20 ].…”

Bisphenols (BPs) are a class of endocrine disruptors widely existing in the environment. They have a great impact on human health owing to their environmental endocrine disrupting effects, chronic toxicity, neurotoxicity, cytotoxicity and genetic toxicity. In this paper, an on-line packed fiber solid phase extraction (PFSPE) coupling with column-switching HPLC-FLD determination method was developed for the determination of eight BPs in drinking water. The poly (dibenzo-18-crown-6-ether)/polystyrene composite nanofibers (PDB18C6/PS) were prepared by electrospinning and used as an adsorbent for the on-line PFSPE column. The on-line PFSPE-HPLC equipment contained a dual ternary pump and a switching valve to enable enrichment, purification, and analysis directly in the system. The results showed that the proposed on-line PFSPE-HPLC-FLD method realized the simultaneous separation and detection of eight BPs: BPF, BPE, BPA, BPB, BPAF, BPAP, BPC and BPZ. The curves of the target analytes were prepared with good correlation coefficient values (r2 > 0.998) in the range of 50–1000 pg/mL. The limit of detection (S/N = 3) was 20 pg/mL, the limit of quantitation (S/N = 10) is 50 pg/mL. The recoveries of eight BPs were 94.8–127.3%, and the intra-day precisions (RSD) were less than 10%. The PFSPE column made of the PDB18C6/PS composite nanofibers has stable properties and can be reused at least 200 times. In the detection of drinking water samples, BPZ was detected in nearly 80% of drinking water samples, and BPA, BPAP, BPF and BPAF were also detected in some water samples. This high level of integration and automation was achieved in pretreatment of eight BPs from water samples. The proposed simple, rapid, and practical method has been successfully applied to the detection of eight BPs in drinking water, which can provide powerful technical support for drinking water quality and safety monitoring.

“…35 Keeping the above facts in mind, it is imperative to develop an effective method for determining BPA from different water samples to manage its potential risk to humans and aquatic life. Various conventional methods have been employed for determining BPA from wastewater and industrial effluents, including adsorption, 38 membrane separation, 39 biological methods, 40 photocatalysis, 41 high-performance liquid chromatography, 42 and electrophoresis. 43 However, these conventional methods have specific bottlenecks; are costly and tedious; and require several preprocesses, sophisticated instrumentation, complex sample preparation methods, and consumption of hazardous organic solvents.…”

Bisphenol A (BPA) is broadly used in the plastic industry and has several health effects, especially on the brain and prostate gland of fetuses. BPA is a major environmental pollutant that drains into bodies of water and leaches from food packaging. Since it is a known endocrine disruptor, its extensive release into the environment is a serious concern. Thus, regular monitoring of BPA through a reliable and sensitive method is a strategy that can help alleviate its impact. To tackle this issue, an excellent conductive material based on a NiO/ZnO/rGO nanohybrid was used as an electrocatalyst to determine BPA in drinking water samples. The engineered material was characterized through XRD, EDX, and SEM. The EDX mapping was also used to examine the purity, surface texture, and focused elemental composition of the NiO/ZnO/rGO nanohybrid. The average size of the prepared material was calculated as 43.7 nm, which confirmed the nanometric size of the engineered nanohybrid material. The conductive behavior of the fabricated sensor NiO/ZnO/rGO/PtE was examined through electrochemical impedance spectroscopy (EIS) and cyclic voltammetry. The modified sensor revealed an excellent conductive nature with ohmic resistance calculated to be 412 Ω, which is lower than that of the bare electrode and GO/PtE (3628 and 2239 Ω, respectively). Under optimal parameters, the fabricated sensor showed excellent response for BPA. With a linear dynamic range of 0.07−30 μM, NiO/ZnO/rGO/PtE manifested the lowest possible detection limit found (4.0 nM). The analytical applicability of the proposed sensor was investigated in bottled and tap water. Furthermore, both the acceptable recovery values and anti-interference ability indicated the effectiveness and potential commercial utilization of NiO/ZnO/rGO/PtE. The recovery values for mineral and tap water were 97.0%, 99.0%, and 97.3% and 101%, 99.6%, and 98.7%, respectively.

“…BPs have been detected in many environments and food media in the range of 14-521 ng/mL (or ng/kg) [4][5][6]. Owing to human-health concerns, the European Commission (2017) decreased the maximum residual limit of bisphenol A (BPA) in food matrices from 0.60 to 0.05 mg/kg [7]. In China, the maximum BP concentration in food contact materials is < 0.60 mg/kg [8].…”
