In this paper, mass transfer in a laminar pulsating flow between two parallel flat plates has been studied. Mass transfer from the fluid to the mass transfer surface was measured by an electro-chemical method, in which the redox system comprises the electrolyte and the test nickel cathode. Measurements were conducted at a Reynolds number of 250, a Schmidt number of 1600 and a Womersley number range of 1.06~10.6. Furthermore, mass transfer was numerically estimated by calculating the diffusion equation. Consequently, the frequency characteristics of mass transfer are similar to those of the first-order time lag system. Owing to pulsating flow, the time-averaged mass transfer is a little lower than that corresponding to steady flow, as the flow amplitude increases and the pulsating frequency decreases.
