Reduction of toxicity of aqueous solutions

Claim 1

A METHOD OF DECREASING THE CONCENRATION OF ANODICALYOXIDIZABLE SPECIES SELECTED FROM FREE AND/OR COMPLEXED CYANIDE IONS, CYANATE IONS AND THIOCYANATE IONS IN AN AQUEOUS SOLUTION THEREOF WHICH COMPRISES: PASSING SAID AQUEOUS SOLUTION ALONG A PLURALITY OF FLUIDLYINTERCONNECTED SUCCESSIVE CONFINED PATHS EACH CONSTITUTED BY AT LEAST ONE PAIR OF ELECTRODES HAVING FACES OF OPPOSITE POLARITY SPACED APART A DISTANCE OF ABOUT 1/16 INCH TO 1 INCH, SAID PASSAGE OF SAID AQUEOUS SOLUTION ALONG SAID PLURALITY OF FLUIDLY-INTERCONNECTED SUCCESSIVE CONFINED PATHS PROVIDING A LAYER OF LIQUOR IMMEDIATELY ADJACENT EACH OF SAID ELECTRODE FACES AND A BULK MASS OF LIQUOR BETWEEN SAID LAYERS, APPLYING D.C. POWER BETWEEN SAID ELECTRODES TO PROVIDE A CURRENT DENSITY OF LESS THAN 200 AMPS PER SQ.FT. TO SAID ELECTRODES, WHEREBY AN ELECTROACTIVE ANODE AND AN ELECTROACTIVE CATHODE ARE PROVIDED, MAINTAINING SAID AQUEOUS SOLUTION AT A FLOW RATE ALONG SAID CONFINED PATHS AND OVER SAID ELECTRODES LESS THAN 5FT/SEC, OXIDIZING SAID ANODICALLY-OXIDIZABLE SPECIES AT SAID ELECTROACTIVEANODE TO PRODUCE MATERIALS INCLUDING GASEOUS MATERIAL, INTERMIXING THE LAYER OF LIQUOR IMMEDIATELY ADJACENT SAID ELECTROACTIVE ANODE WITH SAID BULK MASS OF SAID AQUEOUS SOLUTION TO MINIMIZE PH POLARIZATION AND ANODICALLY-OXIDIZABLE SPECIES CONCENTRATION POLARIZATION BETWEEN SAID BULK MASS AND SAID LIQUOR LAYER IMMEDIATELY ADJACENT SAID ELECTROACTIVE ANODE, SCRUBBING BUBBLES OF GASEOUS MATERIAL FROM BOTH SAID ELECTROACTIVE ANODE AND SAID ELECTROACTIVE CATHODE DURING SAID PASSAGE OF SAID AQUEOUS SOLUTION ALONG SAID PLURALITY OF FLUIDLY-INTERCONNECTED SUCCESSIVE CONFINED PATHS TO FORM A MIXTURE OF SAID GASEOUS MATERIAL AND SAID AQUEOUS SOLTUION AND TO MINIMIZE THE ACCUMULATION OF GASEOUS MATERIAL ON SAID ELECTROACTIVE ANODE AND ELECTROACTIVE CATHODE, CONVEYING SAID MIXTURE OF GASEOUS MATERIAL AND AQUEOUS SOLUTION SUCCESSIVELY ALONG SAID CONFINED PATHS, AND RESTRICTING THE PASSAGE OF SAID MIXURE ALONG SAID CONFINED PATHS BELOW A TOTAL PATH LENGTH ABOVE WHICH THE PROPORTION OF GAS IN THE MIXTURE AT THE EXTREMITY OF SAID PATHS EXCEEDS ABOUT 20 PERCENT.

Claim 2

A METHOD OF DECREASING THE CONCENRATION OF ANODICALYOXIDIZABLE SPECIES SELECTED FROM FREE AND/OR COMPLEXED CYANIDE IONS, CYANATE IONS AND THIOCYANATE IONS IN AN AQUEOUS SOLUTION THEREOF WHICH COMPRISES: PASSING SAID AQUEOUS SOLUTION ALONG A PLURALITY OF FLUIDLYINTERCONNECTED SUCCESSIVE CONFINED PATHS EACH CONSTITUTED BY AT LEAST ONE PAIR OF ELECTRODES HAVING FACES OF OPPOSITE POLARITY SPACED APART A DISTANCE OF ABOUT 1/16 INCH TO 1 INCH, SAID PASSAGE OF SAID AQUEOUS SOLUTION ALONG SAID PLURALITY OF FLUIDLY-INTERCONNECTED SUCCESSIVE CONFINED PATHS PROVIDING A LAYER OF LIQUOR IMMEDIATELY ADJACENT EACH OF SAID ELECTRODE FACES AND A BULK MASS OF LIQUOR BETWEEN SAID LAYERS, APPLYING D.C. POWER BETWEEN SAID ELECTRODES TO PROVIDE A CURRENT DENSITY OF LESS THAN 200 AMPS PER SQ.FT. TO SAID ELECTRODES, WHEREBY AN ELECTROACTIVE ANODE AND AN ELECTROACTIVE CATHODE ARE PROVIDED, MAINTAINING SAID AQUEOUS SOLUTION AT A FLOW RATE ALONG SAID CONFINED PATHS AND OVER SAID ELECTRODES LESS THAN 5FT/SEC, OXIDIZING SAID ANODICALLY-OXIDIZABLE SPECIES AT SAID ELECTROACTIVEANODE TO PRODUCE MATERIALS INCLUDING GASEOUS MATERIAL, INTERMIXING THE LAYER OF LIQUOR IMMEDIATELY ADJACENT SAID ELECTROACTIVE ANODE WITH SAID BULK MASS OF SAID AQUEOUS SOLUTION TO MINIMIZE PH POLARIZATION AND ANODICALLY-OXIDIZABLE SPECIES CONCENTRATION POLARIZATION BETWEEN SAID BULK MASS AND SAID LIQUOR LAYER IMMEDIATELY ADJACENT SAID ELECTROACTIVE ANODE, SCRUBBING BUBBLES OF GASEOUS MATERIAL FROM BOTH SAID ELECTROACTIVE ANODE AND SAID ELECTROACTIVE CATHODE DURING SAID PASSAGE OF SAID AQUEOUS SOLUTION ALONG SAID PLURALITY OF FLUIDLY-INTERCONNECTED SUCCESSIVE CONFINED PATHS TO FORM A MIXTURE OF SAID GASEOUS MATERIAL AND SAID AQUEOUS SOLTUION AND TO MINIMIZE THE ACCUMULATION OF GASEOUS MATERIAL ON SAID ELECTROACTIVE ANODE AND ELECTROACTIVE CATHODE, CONVEYING SAID MIXTURE OF GASEOUS MATERIAL AND AQUEOUS SOLUTION SUCCESSIVELY ALONG SAID CONFINED PATHS, AND RESTRICTING THE PASSAGE OF SAID MIXURE ALONG SAID CONFINED PATHS BELOW A TOTAL PATH LENGTH ABOVE WHICH THE PROPORTION OF GAS IN THE MIXTURE AT THE EXTREMITY OF SAID PATHS EXCEEDS ABOUT 20 PERCENT.
