✦ Synopsis

The electrolysis of 2.0 x lo-' M KsFe(CN), in 1 M KC1 in water at room temperature (22°C) has been investigated on flow-through porous electrodes composed of parallel platinum screens. The effect of changing the number of screens on the limiting current and the limiting degree of conwrsion of substrate has been studied. The results obtained confirm the previously derived model of limiting current on porous electrodes under conditions of solution flow. The experimental results have also been presented in form of mass transfer correlations for Sherwood number and jn-factor. The potential drop in the electrode composed of six screens has been measured and compared with a theoretical equation. The effect of error in the determination of flow rate on the accuracy of presentation of experimental data is discussed. INTRODUCTlON Screens can be applied as efficient electrodes for electrolysis conducted under conditions of solution flow[lL6].
