SARALA, P.  y  VENKATESHA, T.V.. Effect of Cathode Materials on Electrochemical Degradation of Luganil Blue N and Acid Red I. Port. Electrochim. Acta [online]. 2013, vol.31, n.3, pp.175-183. ISSN 0872-1904.  https://doi.org/10.4152/pea.201303175.

The degradation of Acid Red I dye (ARI) and Luganil Blue N (LBN) has been studied by electrochemical treatment methods. The efficiency of cathode materials such as platinum, copper, zinc, lead, graphite, nickel, steel and titanium metals on the degradation of Luganil Blue N and Acid Red I dyes were investigated. The suitable cathode material was chosen and other parameters such as current density, and NaCl and dye concentrations were optimized. The electrolysis process was monitored by UV- Vis spectrophotometer and measuring chemical oxygen demand of the electrolyzed solutions. The overall COD removal efficiencies reached as high as 74.24% and 87% for ARI and LBN, respectively.

Palabras clave : current density; electrolysis; cathode material; Luganil Blue N dye; Acid Red I dye.
