2. Phenol removal from wastewaters by electrochemical oxidation using boron doped diamond (BDD) and Ti/Ti0.7Ru0.3O2 dsa® electrodes
Industrial wastewater containing non-biodegradable organic pollutants consists of highly toxic effluents whose treatment is necessary due to environmental and economical restrictions. In order to treat these effluents, an electrochemical process using a dimensionally stable anode (DSA®) and boron-doped diamond (BDD) electrode was studied. The performance of

5. Electrochemical degradation of textile dye Remazol Orange 3R using different electrodes / Degradação eletroquímica do corante têxtil Alaranjado Remazol 3R utilizando diferentes eletrodos
This paper will present the results obtained for the electrochemical degradation of textile dye Remazol Orange 3R. A filter-press cell was used with different electrodes: platinum polycrystalline, DSA® Ti/Ru0,3Ti0,7O2 and an electrode prepared by the Pechini method (Ti/Pt). The electrode Ti/Pt was prepared by deposition H2PtCl6.6H2O on a Ti substrate and

6. Aplicação da teoria ac de eletrodos porosos na investigação da cinética de dispositivos eletrocatalíticos / Application of ac theory for porous electrode in the investigation in the kinetics of electrocatalytic devises
This work consists in using Electrochemical Impedance Spectroscopy (EIS) in the research of various electrocatalytic materials. The porous electrode model is a very promising approach to treat the frequency responses of Dimensionally Stable Anodes (DSA®). Once the application of the model is established, it is possible to obtain important kinetic informatio

7. Estudo da degradação de ranitidina via H IND. 2 O IND. 2 eletrogerado/fenton em um reator eletroquimico com eletrodos de difusão / Studyof the degradation eletrochemical of ranitidine it saw H IND. 2 O IND. 2 eletrogerado/fenton in an eletrochemical reactor with electrodes of gaseous diffusion
The study of the electrochemical degradation of the ranitidine, a drug used in the therapy of gastric ulcers was development in two steps. In the first step was studied the electrochemical behavior of the ranitidine on platinum (Pt) and glassy carbon (CV) electrodes, using cyclic voltammetry in aqueous (K2SO4 0.1 M) and non-aqueous (NaClO4 0.1 M in DMF) elec

8. Eletrochemical treatament of the cyanide wastewater using commercial noble metal oxide electrodes / Tratamento eletroquimico de efluentes cianidricos usando eletrodos comerciais de oxidos de metais nobres
Inorganic cyanide is still in use in the metal finishing industry and in the mining activities of noble metals extraction and refining. Gold and silver are extracted from its ores as cyanidric complexes. The intensive industrial use of cyanide complexes is responsible for the generation of high toxicity aqueous streams, which present high oxygen demand. The
