Dynamics of variations in the metal deposit distribution in porous flow-through electrodes: Effect of solution flow velocity and direction

Dynamics of variations in the metal deposit distribution in a porous flow-through electrode (PFE) and a number of integral indicators of the process are studied as a function of the velocity of solution flow and the direction of its supply with the aid of a dynamic model for PFE. It is established that qualitative character of variations in the above parameters with time depends on which of two factors (distribution of polarization or concentration of metal ions) predominantly defines the metal electrodeposition process inside PFE. It is shown that employing reverse of solution flow through PFE with the aim of increasing the weight of metal deposited in it and the uniformness of its distribution gives positive effect only in the case where the metal distribution for opposite supply directions is different.
