Silver Antibacterial Properties Influenced by Pulsed Electrodeposition Frequency

Regarding this, we have previously reported the surface characterization and bactericidal properties of electrodeposits of silver over activated carbon particles. Silver deposits were obtained from nitrate solutions using an electrochemical pulsed bed reactor operated at different values of both current intensity and electrolyte flow rate. Carbon/silver samples were obtained by two different electrodeposition strategies: in the first case, the effect of both current intensity and electrolyte flow rate over silver deposition was investigated by keeping the particles still while applying different currents at various electrolyte flow rates; the second case involved a series of current pulses applied to the samples until total deposition time was covered, after each pulse, the particles were repositioned (without current) by fluidization due to changes in the direction of the electrolyte flow.
