The currently recommended concentrations of aftertreatments containing heavy metals often prevent a textile finisher from meeting effluent discharge regulations. This study involved optimizing the application procedures and concentrations of copper sulfate for copperizing direct dyes on cotton and of tartar emetic (potassium antimony tartrate) for insolubulizing tannic acid on dyed nylon. The r...

Economical and bio-friendly approaches are needed to remediate dye-contaminated wastewater from various industries. In this study, a novel bacterial strain capable of decolorizing triarylmethane dyes was isolated from a textile wastewater treatment plant in Greece. The bacterial isolate was identified as Aeromonas hydrophila and was shown to decolorize three triarylmethane dyes tested within 24...

Introduction Azo dyes – a fatal threat or a new generation of drugs? In 1858 Griss developed the azo coupling reaction and obtained first azo dye – Aniline Yellow. Nowadays, around 10 thousands of these compounds are described and more than 2 thousands are applied to color various materials. Azo dyes are characterized by the presence of the azo moiety (–N=N–) in their structure, conjugated with...

El agua es uno de los recursos naturales más preciado, en consecuencia, la escasez algunas regiones sumado a alta concentración elementos y sustancias tóxicas provocados por el mal uso descuido seres humanos amenazan gran medida sustancia vital este planeta. En caso particular industria textil, colorantes empleados (generalmente azoicos) son compuestos tóxicos mutagénicos, además, incrementan v...

The results of wastewater treatment textile enterprises in the electrolyzer with insoluble anodes and separation electrode spaces an inert membrane are presented. influence time, current density, concentration sodium chloride, initial dyes on process electrochemical destruction is determined. developed technology makes it possible to ensure effectiveness organic substances, which necessary obta...
