20.500.12556/DKUM-66661 Magnetic field effects on redox potential of reduction and oxidation agents Utjecaj magnetskog polja na redoks potencijal redukcijskih i oksidacijskih spojeva Redox potentials of two reducing (sodium dithionite and glucose) and two oxidizing (hydrogen peroxide and sodium hypochlorite) agents were monitored at various concentrations and at different temperatures for 30-75 minutes after the exposure of their water solutions (glucose and hypochlorite solutions once; sodium dithionite and hydrogen peroxide solutions one, two and/or three-times) to the static magnetic field of flux density of 0.9 V s M-2 . The aim of the investigation was to suggest improvements, i.e., intensification and stability, of the reduction-oxidation ability of selected agents applicable in textile fibre processing, primarily bleaching and vat dyeing. Results of the experiments show that magnetic treatment (of solutions) raises both the reducing ability of glucose and the oxidation ability of hydrogen peroxide and sodium hypochlorite, promising some technological and economical benefits for the textile industry as well as forother fields of chemistry. Redoks potencijali vodenih otopina dvaju redukcijskih (natrijev ditionat i glukoza) i dvaju oksidacijskih (vodikov peroksid i natrijev hipoklorit) spojeva mjereni su pri različitim koncentracijama i različitim temperaturama 30–75 minuta poslije izlaganja otopina statičnom magnetskom polju gustoće toka 0,9 V s m–2. Otopine su polju izlagane ili samo jednom (glukoza i natrijev hipoklorit) ili jednom, dvaput i triput (natrijev ditionat i vodikov peroksid). Cilj je istraživanja predložiti poboljšanje redukcijske, odnosno oksidacijske sposobnosti odabranih spojeva koji se koriste u obradi tekstilnih vlakana, prvenstveno za izbjeljivanje i bojenje. Rezultati eksperimenata pokazuju da se magnetskom obradom otopina povećavaju redukcijska sposobnost glukoze i oksidacijska sposobnost vodikova peroksida i natrijeva hipoklorita, što bi moglo biti tehnološki i ekonomski korisno tekstilnoj industriji, a zanimljivo ostalim granama kemije. magnetic water treatment sodium dithionite glucose hydrogen peroxide sodium hypochlorite redox potential textile vat processing magnetna obdelava vode natrijev ditionit glukoza vodikov peroksid natrijev hipoklorit redox potencial true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-05 10:40:48 2017-07-05 10:41:36 2022-08-01 13:01:13 2019-07-11 15:54:44 2008 0 0 str. 413-421 št. 3 Letn. 81 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0011-1643 628.3:537.86 22807 12869142 0011-1643 URN:SI:UM:DK:29WBP25T Croatica_Chemica_Acta_2008_Bozic,_Lipus,_Kokol_Magnetic_Field_Effects_on_Redox_Potential_of_Reduction_and_Oxidation_Agents.pdf Croatica_Chemica_Acta_2008_Bozic,_Lipus,_Kokol_Magnetic_Field_Effects_on_Redox_Potential_of_Reduction_and_Oxidation_Agents.pdf 1 C1CB9B80AAE5F32F30734D457E595043 303fbed5a3cc756e79963cc86e52e75a9cf06763690a743daf92f0000dcfa381 5b832bdf-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4568fa7a-1ff1-48d7-9749-9e4914f7469f https://dk.um.si/Dokument.php?lang=slv&id=113672 http://hrcak.srce.hr/31125 1 https://dk.um.si/Dokument.php?lang=slv&id=113671 Fakulteta za strojništvo 0 0 0
