Destruction of nitrate compounts could be carried out in electrochemical redox processing using porous electrodes. Cell performances were calculated from efficiencies of destruction and supplied electrical current. Influent containing 50 ppm of nitrate was flowed through porous carbon fielt and titanium-coated platinum electrodes. The supplied electrical current affected the destruction efficiency. When 2A electrical current was applied, the process efficiency was approximately 85% (for the destruction) and 29.02% (electrical current) but these effisiencies were lower when the supplied current differed. Increasing of pH and solution temperature were observed during the experiments. The coefficients of mass transfer were estimated from the process mass balances and the electrical current. keywords: destruction of nitrate, electrochemical redox processing, porous electrodem electrical current.
