20.500.12556/DKUM-91740 The Bray–Liebhafsky oscillatory reaction as a chemosensor for benzenediols Benezediols are widely used in different areas of industry, thus identification and quantification of benzenediols is of utmost importance due to their toxicity and high environmental abundance. In this work, benzenediol isomers (pyrocatechol, resorcinol, and hydroquinone) were investigated by using the Bray–Liebhafsky (BL) oscillatory reaction. All three isomers exhibit different behavior in the BL reaction, which renders the BL system applicable as a chemosensor. The period between the fifth and sixth oscillation, the amplitude of the sixth oscillation and in the case of hydroquinone, the emergence of a new oscillation in the BL reaction were selected as the parameters used for the identification and quantification of these isomers. Furthermore, electron paramagnetic resonance spectroscopy and DFT calculations were performed in order to provide insights into the mechanism of benzenediols reactions with the BL system. oscillatory reactions Bray–Liebhafsky reaction benzenediols chemical sensors radical scavenging oscilatorji Bray–Liebhafskijeva reakcija kemijski senzorji radikali true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/chemosensors © 2024 by the authors Članek v reviji 2025-01-31 10:57:42 2025-01-31 10:57:42 2025-08-27 09:37:06 0000-00-00 00:00:00 2024 0 0 18 str. iss. 10, [article no.] 211 Vol. 12 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-09-02 2024-10-09 2024-10-15 544 212964355 10.3390/chemosensors12100211 2227-9040 chemosensors-12-00211.pdf chemosensors-12-00211.pdf 1 DA1799113026CA2359F1C745DBD791C5 f5b598f899fbbf0aee778b6d518a66cece513750f35809ae00b569f75545b96b c667c56f-dfba-11ef-ae92-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188366 https://www.mdpi.com/2227-9040/12/10/211 0 8cea1007-8317-11f0-8e8c-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=196544 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
