Abstract

An accurate and rapid method for detg. the diffusion coeffs. of electrochem. active gases in electrolytes is described. The technique is based on chronoamperometry where transient currents are measured and interpreted with a Cottrell-related equation. The diffusion coeffs. of oxygen were detd. for 0.085 - 0.846 M NaCl solns. at 20-40 DegC. A relationship for the diffusion coeff. of oxygen as a function of temp. is given for the several NaCl concns
