Graphite/NiO/Ni electrode had been fabricated for the electro-oxidation of remazol black 5 dye. The was synthesized by electrodeposition method. Electro-oxidation 100 ppm dye carried out at various concentrations NaCl, 0.025; 0.05; 0.1; 0.25; and 0.5 M, variations in time were 15, 30, 45, 60 minutes, pH 4, 6, 8. Cyclic voltammetry test revealed that graphite/NiO/Ni higher electrocatalytic capab...
