Abstract: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.

Title:Utjecaj magnetskog polja na redoks potencijal redukcijskih i oksidacijskih spojeva
Abstract: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.
Keywords:magnetna obdelava vode, natrijev ditionit, glukoza, vodikov peroksid, natrijev hipoklorit, redox potencial
