“…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.

“…Thus, in these cases using stated advantages specifically their short needed time for response providing even direct determination of these targets could be possible [162] . In these techniques, voltammetric and background signals are split in to the frequency domain by a separate FFT, and then the systematic inevitable noise could easily be filtered [163] , [164] , [165] , and all analog filters could be removed from the electrochemical system for reach to a small potentiostat that can have effective role for miniaturizing the systems and their relative applications in medical devices [166] , [167] . Also, low concentrations of the analyte in complicated matrix specifically in the cases of biological samples such as blood serum, urine and plasma is one of the most serious challenges in these kinds of research studies [189] .…”

For the first time, a sensitive electrochemical sensor using a glassy carbon electrode modified with CMK-5 Ordered mesoporous carbon was fabricated for simultaneous analysis of morphine and methadone. Modern electrochemical FFT-SWV techniques and partial least-squares as a multivariable analysis were used in this method. CMK-5 nanostructures were characterized by field emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis, and Raman spectroscopy. Variables such as accumulation time and pH for the proposed sensor were optimized before quantitative analysis. To train the proposed sensor, standard mixtures of morphine (MOR), and methadone (MET) were prepared in the established linear ranges of the analyzes. The results obtained from training samples were used for PLS modeling. The efficiency of the model was determined using test and real matrix samples. The root mean square error of prediction and the squared correlation coefficients (R2p) for MET and MOR were estimated to be 0.00772 and 0.00892 and 0.948 to 0.990, respectively. The recoveries in urine samples were reported to be 97.0 and 105.6% for both MOR and MET, respectively.
