QUIROZ, Marco Antonio; MARTINEZ-HUITLE, Uriel Alejandro  and  MARTINEZ-HUITLE, Carlos Alberto. Mass Transfer Measurements in a Parallel Disk Cell Using the Limiting Current Technique. J. Mex. Chem. Soc [online]. 2005, vol.49, n.3, pp.279-283. ISSN 1870-249X.

Mass transfer measurements in electrochemical cell using a different design and Reynolds numbers have been made in a parallel plate cell of disk geometry. The cell has only one inlet and exit, which produces extremely complex hydrodynamics in the cell. The mass-transfer coefficient was obtained using limiting diffusion current technique based in ferricyanide ion reduction, also overall mass transfer coefficients were correlated to the Reynolds number range between 80 to 1039. Here, we have made a theoretical approximation of the mass-transfer coefficient for disk geometry using the Levique relation. Finally, the disk design cell has showed improvements in the mass transfer coefficient.

Keywords : Electrochemical cell; limiting diffusion current technique; Mass transfer coefficient; Engineering parameters.
