Claims
- 1. A hydrophilic electrochemical filter matrix, consisting of:
- carbon fibers in the 2 .mu. to 30 .mu. fiber diameter range; and,
- carbon or graphite particles in the 100 .ANG. to 5,000 .ANG. particle size range attached to the surface of said carbon fibers, such attachment of said particles resulting in an increase of the surface area of the filter from the range of abut 1 m.sup.2 /g to about 10 m.sup.2 /g, wherein the filter is characterized by a high electrical conductivity due to the carbon-particles to carbon fiber bond, and by a substantially free pathway of liquids flowing through the filter matrix.
- 2. The filter matrix of claim 1, wherein the carbon fibers have a diameter int he range of about 5 .mu. to 15 .mu. fiber diameter range.
- 3. The filter matrix of claim 1, wherein the particle size is about 800 .ANG..
- 4. The filter matrix of claim 1, wherein the particles are attached to the surface of the carbon fiber with a binder selected from the group consisting of sugars, resins, gums, an polymers.
