Azo dyes Azo dyeingallows the indigo to penetrate very deeply into the thread. During the dyeing process, the threads to be dyed is moved through a chamber filled with nitrogen, and this is accompanied by a chemical oxidization reaction. The pigment reacts to the oxygen and the dyeing proce...
Fenton, photo-Fenton, TiO2, TiO2-UV-H2O2, TiO2-ZnO, and electrochemical methods have been successfully applied for the degradation of dyes and textile effluents (Chavaco et al.2017; Habibi and Mikhak2012; Manenti et al.2015; Saien and Soleymani2007). Nonetheless, the number of photo-assisted...
dyes, auxiliaries and other chemicals added to the textile processing process may cause the textile to contain carcinogenic azo dyes, human allergic dyes, toxic and harmful chemicals with chronic toxic formaldehyde and heavy metals. They suggested that if a strange smell of water has not disappeared...
