V. Lescuras et al., A PHOTOPHYSICAL TECHNIQUE FOR THE MEASUREMENT OF LOCAL OXYGEN CONCENTRATION NEAR AN ELECTRODE SURFACE, Journal of Applied Electrochemistry, 24(7), 1994, pp. 652-657
Electrochemical processes involving gas production are of great techni
cal importance but the mechanisms involved in the growth of electrogen
erated bubbles and transport processes involving gas near an electrode
still remain obscure. This paper describes an original technique, bas
ed on the inhibition of the fluorescence of an appropriate substance b
y dissolved oxygen, for the measurement of the local concentration of
dissolved oxygen near an electrode. The possibilities offered by this
technique and typical results are presented and discussed.
