Direct Orange 39) by reductive process (Na2SO3) under ultraviolet radiation (254 nm) in a recirculating photoreactor; was investigated in this study. The effects of operational parameters, such as: sulfite concentration, pH values and treatment time were experienced with a focus on removing the color. The best conditions selected in this study were: Higher percentage of color removal (410 nm absorbance) in the mixture of textile dyes 30% and turbidity was 90% ̈using 1.0 mmol L-1 of sodium sulfite at pH 3.0 during 120 minutes of treatment.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Indústria têxtilDegradaçãoTratamentoReatorTextile industryDegradationTreatmentReactorArtigo
