Modelización de la electrodisolución del cinc en medio ácido.

The use of the F(dm/dQ) function has been applied in the analysis of the Electrochemical Quartz Microbalance (EQCM) response, which proportionate a estimation of the atomic weight of the species involved in a faradaic transfer. Thus, it is studied in depth the zinc electrodeposition as well as its anodic dissolution, this one has allowed to postulate the formation of a new phase of Zn(I) in the zinc anodic dissolution process of different galvanized. The dissolution kinetics has been quantified by means of the realization of EIS experiences and the contrast of two models: a) the deduction (from kinetics laws) of the theoretical electrochemical impedances function and b) the use of equivalent circuits. Accordingly, the Z(w), Y(w) and C(w) functions have been analyzed. Furthermore, the electrodic system ES F PB has been studied in depth due to the fact that it is considered a theoretical model in the study of electroactive films.
