RESUMO:

Due to the great concern with environmental issues and with the removal of potentially contaminating compounds from water bodies, among these, the cosmetics used in the various procedures performed in beauty salons, several studies related to the treatment of effluents and contaminated surface waters have been developed in the recent years, according to Durán (2018). And among the alternatives of great interest are the electrochemical processes, which are basically based on the application of methods that are capable of generating •OH radicals, since these have great oxidizing potential, capable of degrading organic compounds present in the effluents to be treated, reaching sometimes total mineralization. Many procedures can be applied to treat these residues from beauty procedures, but this article focuses on the use of electrochemical oxidation, more specifically in anodic oxidation, through Boron Dopped Diamond (BDD) anodes and Dimensionally Dimensional Anodes. Stables (DSA) for the treatment of a real effluent, from a hair coloring process, collected at the time of rinsing, from a beauty salon in the city of Assú/RN. For the oxidations carried out in this work, three current densities were applied, these being 30 mA.cm-2 , 60 mA.cm-2 and 90 mA.cm-2 . Within the study, it was observed the need to use the electrolyte Na2SO4 for current conduction. After the experimental tests, the following parameters of the treated samples were observed: pH, potential and COD. Significant results were obtained, as follows: the test performed with a BDD anode, with a density of 90 mAcm-2 , removed about 96,5% of organic matter present in the sample, but the cost was R$87.07/hour. In the test with the DSA anode, about 90% of organic matter was removed, using a lower current density, only 60 mAcm-2 and a cost of R$15.22/h. The use of the DSA anode becomes much more viable if we take into account the costs, and it is also quite efficient.
