Electrocristallization of copper from non-cyanide alkaline solution containing glycine

Résumé

A thermodynamic study by means of potential-pH (Pourbaix type) and species repartition diagrams is presented in this work with the view to better understand the electrodeposition of copper from noncyanide alkaline solution containing glycine. The parameters studied were glycine concentration, temperature and scanning rate. The voltametric studies also indicate control by diffusion for the copper electrodeposition. In order to compare the effect of the temperature, we measured the kinetic parameters: charge transfer coefficient (αc) and rate constant ( ). The morphological study indicated that the temperature plays a role on grain size of the copper coating obtained. X-ray diffraction studies showed that the deposit obtained at 40°C has a crystallite structure, which differs from that found at 25°C
