Here, Pd nanoparticles and poly(taurine) film was prepared on the glassy carbon electrode surface (Pd/Poly(TAU)/GCE) by the rapid electrochemical technique. The proposed composite surface was characterized by scanning electron microscopy(SEM), X‐ray photoelectron spectroscopy(XPS) and electrochemical impedance spectroscopy(EIS). Enhanced electron transfer ability and higher electroactive surface area were achieved at Pd/Poly(TAU)/GCE as compared to the bare GCE and polymer film electrode. The new and highly stable Pd/Poly(TAU)/GCE was employed for the individual and simultaneous determination of hydroquinone and catechol which were environmentally toxic. Under the optimized conditions, HQ and CC were individually determined by using the differantial pulse voltammetry in the linear ranges of 0.008–100 μM and 0.001–100 μM with the detection limits of (LOD) 2.1 nM and 0.68 nM, respectively. In case of simultaneous determination, LODs were found as 10 nM and 0.88 nM for HQ and CC, respectively. The content of both analytes in the real sample analysis was evaluated in the river water and tap water successfully.

“…HQ (1,4‐dihydroxybenzene) is an isomer of dihydroxybenzene that was first discovered in 1820 by Pelletier and Caventou through the dry distillation of quinic acid. HQ possesses anticancer, anti‐inflammatory, antioxidative, and neuroprotective properties [3,4] and is used as an essential raw material in different industries such as cosmetics, rubber, coal tar, leather, pharmaceuticals, and medicine [5–7] . An excess of HQ is used in cosmetics to improve bleaching capacity, but long‐term cosmetics use has been found to lead to skin damage or severe allergies [8,9] .…”

“…Every year, a large amount of HQ is released into the environment as an industrial effluent. During its release in the environment, HQ is absorbed by different organisms, resulting in adverse effects on human and marine life, even at low concentrations [5,12] . HQ can also be formed in the early stage of phenol oxidation, making it even more widespread in nature.…”

“…Therefore, highly susceptible analytical methods for the simultaneous and selective detection of these three isomers are necessary. Different analytical techniques are applied for the selective, simultaneous detection of HQ, CT, and RS, such as high‐performance liquid chromatography (HPLC), [3,42,45,50,64] chemiluminescence, [37,43,47,52,65] spectrophotometry, [35,38,44,47,53] fluorescence, [17,33,39,51] gas chromatography/mass spectrometry (GC−MS), [15,22,46,51,63] pH‐based flow‐injection analysis, [29,40,57,71] capillary electrophoresis, [5,24,54,62] UV‐Vis spectroscopy, [56] colorimetry, [55,68] and electrochemical techniques [37–47,58–61,65–70] …”

Dihydroxybenzene is regarded as a serious environmental pollutant. Its detection through electrochemical methods is still challenging due to having a similar structure and overlapping signals with the conventional bare electrode. Thanks to the unique features and wide applicability of carbon nanotubes, graphene, and their derivatives, they can be used as modifiers to overcome the poor resolution ability of bare electrodes in the detection of dihydroxybenzene. This review focuses on the use of carbon nanotubes, graphene, and their derivatives and nanocomposites to enhance the electrocatalytic activity of conventional bare electrodes for dihydroxybenzene sensing. The reports from 2011–2020 on the simultaneous and/or individual detection of three different dihydroxybenzenes – hydroquinone, catechol, and resorcinol – are summarized. This review also highlights the challenges and prospects surrounding the sensitive and selective detection of dihydroxybenzene.

A Novel Self‐protection Hydroquinone Electrochemical Sensor Based on Thermo‐sensitive Triblock Polymer PS‐PNIPAm‐PS

A novel self‐protection sensor was successfully constructed based on an interesting thermo‐sensitive triblock polymer PS‐PNIPAm‐PS. At low temperatures (<24 °C), the analyte was able to undergo the redox process at the modified electrode. However, the polymer shrunk and accumulated at high temperatures (>30 °C), which dramatically increased the electron transfer resistance (Rct) of the modified electrode and consequently blocked the occurrence of the redox reaction to protect the electrode from high temperatures and enhance its stability. Under optimized conditions, the proposed sensor showed a good detection range for hydroquinone (6×10−7 to 2.35×10−3 M) and a low LOD (490 nM). The sensor was also successfully applied for detecting hydroquinone in real samples. The present work may provide a novel method for electrode protection, high‐temperature alarm, high‐temperature protection of batteries and new sensors production.
