USM ADMIN
The processes of catalytic oxidation of textile colorant orange active (PA) wizh hydrogen peroxide were studied, in depemdence on the concentration of hydrogen peroxide, iron (II), initial concentration of colorant, with and without subsequent boiling of model solutions. It was found that the effect of de-coloration and mineralization degree of colorant PA depends on concentration of hydrogen peroxide and colorant. Maximal mineralization reached was 84-85%. In case of subsequent boiling of model solutions, following their catalitic oxidation, mineralization degree was increased reaching up to 97-98% in 5-minutes time.
