Abstract
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 UVVis 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.
