Decolourization of Anthraquinone Reactive Dye by Electrochemical Reduction on Reticulated Glassy Carbon Electrode
A remoção do corante reativo Reactive Blue 4 (RB4) por redução eletroquímica em solução aquosa foi investigada sobre eletrodo de carbono vítreo reticulado. O grupo antraquinona presente no corante RB4 é reduzido em pH < 8,0 em uma única etapa a hidroquinona, segundo um processo reversível de dois elétrons e reação de pré-protonação, via geração de um radical semiquinona detectado espectrotométr...
متن کاملDecolourization and biodegradation of Navy blue HER (Reactive Blue 171) dye from Marasmius sp. BBKAV79
White rot fungus Marasmius sp. BBKAV79 (GenBank accession number-KP455496, KP455497) exhibited decolourization and degradation of Navy blue HER dye (concentration 50 mg l-l) within 24 h under shaking condition. In the present study, various investigated parameters like initial dye concentration, pH, temperature, carbon and nitrogen sources were optimized to develop a faster decolourization proc...
متن کاملElectrochemical Degradation of Reactive Blue 19 Dye in Textile Wastewater
Textile wastewater is notoriously known to contain strong colour, a highly fluctuating pH and significant COD (Chemical Oxygen Demand) values. Because of these characteristics, treatment of these effluents has been rather difficult. Traditional methods for dealing with textile wastewater consist of various combinations of biological, physical and chemical methods. Because of the large variabili...
متن کاملDegradation of Anthraquinone Dye Reactive Blue 4 in Pyrite Ash Catalyzed Fenton Reaction
Pyrite ash (PA) is created by burning pyrite in the chemical production of sulphuric acid. The high concentration of iron oxide, mostly hematite, present in pyrite ash, gives the basis for its application as a source of catalytic iron in a modified Fenton process for anthraquinone dye reactive blue 4 (RB4) degradation. The effect of various operating variables such as catalyst and oxidant conce...
متن کاملTrypan Blue Dye Enters Viable Cells Incubated with the Pore-Forming Toxin HlyII of Bacillus cereus
Trypan blue is a dye that has been widely used for selective staining of dead tissues or cells. Here, we show that the pore-forming toxin HlyII of Bacillus cereus allows trypan blue staining of macrophage cells, despite the cells remaining viable and metabolically active. These findings suggest that the dye enters viable cells through the pores. To our knowledge, this is the first demonstration...
