diffusion current constant

in polarography
The empirical quantity defined by the equation
i = i d , l c B m 2 3 t 1 1 6
where i d , l = limiting diffusion current, c B = bulk concentration of the substance B whose reduction or oxidation is responsible for the wave in question, m = average rate of (mass) flow of mercury (or other liquid metal) and t 1 = drop time.
