ABSTRACT:
A sensor and method are disclosed for measuring electrokinetic effects across a double layer formed at the boundary between a solid wall and an ionic liquid flowing through a channel. In one embodiment, a passive electrode is located in a cavity forming a tee section with the channel through an orifice of approximately the same size as the channel. A passive second electrode in electrical communication with one side of the double layer is placed on the other side of a porous plug which is located in a second cavity directly opposite the orifice and which is flush with the channel walls. The double layer being investigated is formed on the flush portion of the porous plug. Thus both electrodes are out of the flowing liquid. An electrokinetic potential, labeled the K-effect potential, was measured by the two electrodes. In one use of the sensor, monitoring this potential, the chemical composition of the liquid can be maintained so as to keep a desired surface charge on suspended minerals which are being processed.
