Porous inert electrodes





2005

I want to run an electroosmotic flow through powdered resin of 35-50 micron particle size. Can I support my resin between two inert electrodes which have a pore size smaller than this? These inert electrodes should come in the form a disc and resins can be compressed between the two electrodes. Water will flow through the electrode-resin-electrode configuration.

Where can I get such and electrode? Is porous carbon electrode suited? Can they support 0.1-0.5 Amps current?

Please suggest

Carbon can corrode. It probably won't endure 0.5 amps in a 1 inch disc. Do you really want that much electrolysis happening right in your stream?
It makes a little more sense to me to try to separate the powder-support function from the electrode function.
Purchase any thin micro-porous filter disc, support it with a thicker disc with large pores, and support that with glass frit disc. All non-conductive. have nont-necessarily porous electrodes farther downstream or off in some side-branch.

Jim,
I agree that the resin-support function can be separated from the electrode system. But I expect huge voltage loss if the resin is supported on a polymer frit. The electrodes need to be sitting behind the resin for effective voltage utilization.
What thickness of the carbon electrode you think will withstand a current of 0.5-0.75Amps.
