Abstract
In this work, the indirect oxidation of two azo dyes (Colour Index Reactive Orange 4 and 13) was performed in an electrochemical batch cell in the presence of chloride as an electrolyte. The effect of different operational parameters on the electrochemical treatment was tested. Kinetic plots consisting of two linear portions were obtained in some experiments. The rate constants and the breaking point between the two linear portions were modelled to evaluate the influence of dye concentration, co...
