Effect of sodium dodecylsulfate on copper corrosion in sulfuric acid media in the absence and presence of benzotriazole
TL;DR: In this paper, the effect of sodium dodecylsulfate (SDS) on the copper corrosion in 0.5 mol dm−3 H2SO4 solution has been studied by electrochemical and in situ Raman spectroscopic measurements.
Journal ArticleDOI
Sodium dodecylsulfate–benzotriazole synergistic effect as an inhibitor of processes on copper ∣ chloridric acid interfaces
TL;DR: In this article, the copper-hydrochloric acid interface has been studied in the presence of SDS, benzotriazole and SDS+BTAH mixtures.
Journal ArticleDOI

Ruth Flávia Vera Villamil,G.G.O. Cordeiro,J.B. Matos,Eliane D'Elia,Sílvia Maria Leite Agostinho +4 more
TL;DR: In this article, the effect of sodium dodecylsulfate (SDS) on copper corrosion in sulfuric acid media has been studied in the absence and presence of benzotriazole (BTAH), at room temperature using electrochemical impedance and surface tension (γ) measurements.
Journal ArticleDOI
O eletrólito suporte e suas múltiplas funções em processos de eletrodo
Sílvia Maria Leite Agostinho,Ruth Flávia Vera Villamil,Augusto Agostinho Neto,Hernani Aranha +3 more
TL;DR: In this paper, the principal properties and applications of supporting electrolytes (SE) to students, teachers and researchers interested in electrode processes are discussed, including the importance of SE in maintaining constant the activity coefficients and the diffusion coefficients and reducing the transport number of electroactive species.
