“…Then, an extensive range of electrolytes have been employed such as H 2 SO 4 [32,33], KNO 3 [34], HClO 4 [27], NaF [32], Na 2 SO 4 [17,[35][36][37][38][39][40][41] and NaCl (or KCl) [35][36][37][41][42][43][44][45][46][47][48][49]. From all these supporting electrolytes, the role of chloride is important since the colour removal and degradation degree of azo dyes obtained may be enhanced.…”

“…A wide range of electrolytes are employed for the electrochemical degradation process, such as KNO 3 [24], H 2 SO 4 [25,26], Na 2 SO 4 [16,[27][28][29][30][31][32] NaCl, KCl [27][28][29][32][33][34][35][36][37][38][39][40], NaNO 3 , Na 2 CO 3 , KBr, KI, NaOH and CaCl 2 . Of these the chloride-based electrolytes are preferred, since they enhanced the colour removal and degradation efficiency of azo dyes.…”

“…Antes de la reutilización del agua decolorada en el proceso de tintura, es imprescindible realizar una reconstitución del baño, que consiste en la eliminación de todo el cloro disuelto y otros oxidantes residuales, con el fin de conseguir una mayor intensidad en las tinturas, reponiendo finalmente la cantidad de colorante, electrolito, álcali y agua necesarios para realizar nuevamente el proceso de tintura. Para ello, dispone de un sistema de control (8) y los dosificadores (3,4) correspondientes. -Finalmente se lleva a cabo la reutilización del agua decolorada y del electrolito que ésta contiene en un nuevo proceso de tintura.…”
