Abstract:

The purpose of this study was to determine if the migration and removal of dissolved copper in a saturated porous medium could be controlled electrochemically with an acceptable expenditure of electrical current. The theoretical discussion attempted to provide a complete survey of the factors which affect the movement and removal of metal ions in a saturated porous medium using electrochemistry. Some of these factors did not apply to the experimental work performed in this study, but they were discussed because of their possible effects on the field utilization of the proposed electrochemical technique of pollution control. A series of experiments were performed to demonstrate the relationship between passive Eh and induced EMF as they are used in this study. Using two platinum electrodes with a constant direct current potential induced between them, it was shown that the voltage of each individual electrode could be measured relative to a reference electrode. The voltage of the individual platinum electrode relative to the reference appeared to be a function of the type of solute, the concentration of the solute, and distance between the platinum and reference electrodes.
