“…The corresponding calibration plots at the applied potential of 0.11 V, 0.21 V and 0.83 V for HQ, CC and KNO 2 were calculated in Figure 6d-f The performances of PPC-900/GCE were compared with other reported HQ and CC electrochemical sensors. As showed in Table 1, [3,27,[63][64][65][66][67][68] The PPC-900/GCE sensor not only exhibited the best linear range, but also possessed excellent limit of detection (LOD) among the selected researches. Meanwhile, the PPC-900/GCE also exhibits the excellent performance of nitrite which compared with other reported sensors are listed in Table 2.…”

In this study, popcorn‐derived microporous carbon (PPC) was prepared by pyrolysis method under KOH activation, which was used as an electrochemical sensor material for simultaneous detection of hydroquinone (HQ), catechol (CC), and nitrite (NT). The prepared PPC/GCE exhibited highly electrocatalytic activity to the oxidation of HQ, CC and nitrite. The oxidation peaks for HQ (111 mV), CC (216 mV), and NT (854 mV) were well separated under the optimized conditions. The PPC/GCE showed a wide linear range of 3.0–700 μM, 3.0–500 μM and 5.0–10000 μM for HQ, CC and NT with detection limits of 1.45 μM, 0.49 μM and 1.5 μM, respectively. The KOH‐activated PPC is a promising electrode material for fabricating selective and sensitive electrochemical sensors.

“…Hydroquinone (HQ), resorcinol (RC), and catechol (CC) are extensively used in tanning, metallurgy, petrochemicals, and cosmetics. [1][2][3][4] Ingestion of these isomeric compounds even at a miniscule level is detrimental owing to their genotoxicity, carcinogenicity and poor degradability. 5 A literature survey revealed the involvement of HQ, CC, and RC in causing headaches, fatigue, acute myeloid leukemia, gastrointestinal tract degeneration, liver malfunction, hemolysis, and DNA damage.…”

“…Cheng et al constructed an electrochemical sensor by electrodeposition of dendritic Au nanostructures (DGNs) and electropolymerization of PEDOT consecutively on GCE (PEDOT/DGNs/GCE). The constructed sensor with a dendritic structure, large surface area, and good conductivity, displayed high sensitivity for the detection of dihydroxybenzene isomers 124 with a lower LOD of 9.5 × 10 −7 M for HQ, 1.6 × 10 −6 M for CC, and 1.3 × 10 −6 M for RS. Finally, their sensor showed acceptable results for a successful application to determine dihydroxybenzene in cosmetic samples with satisfactory results.…”

The human population is generally subjected to diverse pollutants and contaminants in the environment like those in the air, soil, foodstuffs, and drinking water. Therefore, the development of novel purification techniques and efficient detection devices for pollutants is an important challenge. To date, experts in the field have designed distinctive analytical procedures for the detection of pollutants including gas chromatography/mass spectrometry and atomic absorption spectroscopy. While the mentioned procedures enjoy high sensitivity, they suffer from being laborious, expensive, require advanced skills for operation, and are inconvenient to deploy as a result of their massive size. Therefore, in response to the above-mentioned limitations, electrochemical sensors are being developed that enjoy robustness, selectivity, sensitivity, and real-time measurements. Considerable advancements in nanomaterials-based electrochemical sensor platforms have helped to generate new technologies to ensure environmental and human safety. Recently, investigators have expanded considerable effort to utilize polymer nanocomposites for building the electrochemical sensors in view of their promising features such as very good electrocatalytic activities, higher electrical conductivity, and effective surface area in comparison to the traditional polymers. Herein, the first section of this review briefly discusses the most important methods for polymer nanocomposites synthesis, such as in situ polymerization, direct mixing of polymer and nanofillers (melt-mixing and solution-mixing), sol–gel, and electrochemical methods. It then summarizes the current utilization of polymer nanocomposites for the preparation of electrochemical sensors as a novel approach for monitoring and detecting environmental pollutants which include heavy metal ions, pesticides, phenolic compounds, nitroaromatic compounds, nitrite, and hydrazine in different mediums. Finally, the current challenges and future directions for the polymer nanocomposites-based electrochemical sensing of environmental pollutants are outlined.
