Measurement of Diffusion Coefficients by DC and EHD Electrochemical Methods
Résumé
The electrohydrodynamic (EHD) method of measuring the Schmidt number is compared carefully with the dc method using a rotating disk electrode. Ferricyanide and ferrocyanide ions in 1M potassium chloride are used for the comparison. The best agreement between the two methods occurs when the EHD measurement is done at a low disk velocity.
