| contents | Study of copper deposit on a porous electrode of carbon and stainless steel by SEM-XRD and image analysis Robinson Constanzo-R. Antonio Pagliero-N. Froilán Vergara-G. Ingeniería Porous electrode current distributio n potential distribution The purpose of this work was to make a qualitative analysis of the distribution of copper deposit inside of stainless steel an d graphite porous electrodes. For that, representative sections of steel and grap hite samples were analyzed by stereoscopic microscopy, SEM-XRD analysis and image analysis by software Scentis Struers Software®. The analysis sh owed that the copper is not deposited uniformly over the electr ode thickness. For steel electrode, the deposit depth in the thickness was around 50%, while graphite electrode about 90% of the thickness. In ge neral, an increase of the deposit towards the end facing the anode was observed and with different sites of copper deposit growth. This behavior shows a current and voltage distribution which is a function of the physical parameters of electrode, and physicochemical and hydrodynamic characteristics of the electrolyte. 2014 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49632363004 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.187 Vol.81 |
