Chemiluminescence of graphene quantum dots induced by acidic potassium permanganate and its application to quenchometric flow-injection assays of hydroquinone in water

Ag and N-doped carbon dot-enhanced H2O2–Co2+ chemiluminescence and its application for the determination of Co2+ and hydroquinone

“…1,2 HQ, essential in industries like dyes, pharmaceuticals, cosmetics, and rubber, is environmentally toxic and may enter the human body. 3,4 Multiple methods like flame atomic absorption spectrometry (FAAS), 5 UV-vis spectrophotometry, [6][7][8] fluorescence (FL) methods, [9][10][11][12] chemiluminescence (CL) methods, [13][14][15] and electrochemical detection (ED) 16,17 are available for Co and HQ analysis. The pursuit of more accurate and sensitive techniques continues.…”

A Cu-functionalized MOF and multi-walled carbon nanotube composite modified electrode for the simultaneous determination of hydroquinone and catechol

“…5 Therefore, developing an easy, fast, sensitive, accurate, and low-cost analytical measurement for determining diphenol isomers is urgently necessary. At present, spectrophotometry, 6 high-performance liquid chromatography, 7 mass spectrometry, 8 capillary electrophoresis, 9 fluorescence, 10 electrochemistry, 11 and other methods have been used to detect dihydroxybenzene isomers. Among these methods, researchers widely favor electrochemical analysis because HQ and CT are highly electrochemically active; meanwhile, electrochemical methods possess the merits of simple instrumentation, rapidity, high sensitivity, and low cost.…”

Continuous and Rapid Synthesis of UiO-67 by Electrochemical Methods for the Electrochemical Detection of Hydroquinone

“…Therefore, it is important to accurately detect the presence of HQ in watershed. Although various detection methods, such as high-performance liquid chromatography (HPLC), spectrophotometry, fluorescence spectroscopy, and electrochemical detection, , have been applied to detect HQ, the electrochemical detection of HQ has received more attention because of its simple operation, low cost, fast response, selectivity, and high sensitivity. , Because it is a fact that the key point of electrochemical detection depends on the electrode materials, it is crucial to develop new electrode materials with high selectivity, good stability, and low cost . MOFs, as famous types of crystalline and porous materials, have been fabricated into electrodes for the electrochemical detection of various chemicals.…”
