Mass Transport And Potential Studies In A Flow-Through Porous Electrode Reactor. Effect Of The Carbon Particle Size, Used As A Porous Cathode, During The Deposition Of Silver Ions

The mass transport and potential characterization were carried out in a flow-through porous electrode reactor. Carbon particles of three different sizes were used as porous electrode. Silver electrodeposition from an alkaline ammonia electrolyte is used as a test system. The experimental mass transport characterization (k(m)a = bu(c)) showed that the value of the coefficient b depends on the magnitude of carbon particle, while c indicates that the flow pattern is a complex function of the carbon particle size. The experimental potential drop in the flow-through porous electrode is also reported. The mass transport and potential characterization have been conducted to identify suitable operating conditions.
