Sažetak

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 for other fields of chemistry.
