Abstract

The minimum concentration attainable in a porous flow-through reactor is estimated by applying the thermodynamics of electrochemical cells with a knowledge of the maximum reactor operating potential. This predicted concentration is the equilibrium wall concentration at the back of the reactor and is qualitatively compared to the experimentally measured minimum average bulk values observed by various authors for the deposition of copper, silver, lead, and mercury, and for the oxidation of ferrous ions. It is suggested that a knowledge of the current versus reactor operating potential will elucidate the lower limits observed for any metal system. In particular, the case of antimony removal is discussed.
