Abstract
Abstract In an electrolytic cell, an electrolyte is caused to flow between an anode and a cathode. The conventional separator between the anode compartment and the cathode compartment can be eliminated, thus allowing circulation of a dispersed electrode throughout the electrolytic cell and obviating the drawbacks resulting from the use of a separator. The dispersed electrode is constituted by a suspension of conductive particles in said electrolyte.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
94 words
An electrolysis method for electrolytic oxidation or reduction of at least one compound in solution comprising circulating the solution through a vessel containing at least two electrodes immersed therein transversally to the direction of flow, polarizing the electrodes to opposite polarities wherein the solution flows freely through perforations provided in each of said electrodes and additionally admixing particles of a dispersed electrode to the solution upstream of the vessel, circulating said dispersed electrode together with the solution through said electrodes in said vessel, and separating said dispersed electrode from the solution, downstream the vessel.
Claim 2
Dependent Claim
94 words
An electrolysis method for electrolytic oxidation or reduction of at least one compound in solution comprising circulating the solution through a vessel containing at least two electrodes immersed therein transversally to the direction of flow, polarizing the electrodes to opposite polarities wherein the solution flows freely through perforations provided in each of said electrodes and additionally admixing particles of a dispersed electrode to the solution upstream of the vessel, circulating said dispersed electrode together with the solution through said electrodes in said vessel, and separating said dispersed electrode from the solution, downstream the vessel.
Claim 3
Dependent Claim
16 words
A method according to claim 1, wherein said solution is an effluent to be electrolytically purified.
Claim 4
Dependent Claim
25 words
The method according to claim 1 wherein the polarity of said dispersed electrode is determined by the direction of the reaction having the faster rate.
Claim 5
Dependent Claim
19 words
The method according to claim 1, wherein both an oxidation reaction and a reduction reaction occur in said vessel.
Claim 6
Dependent Claim
26 words
The method according to claim 1, wherein said solution containing at least one compound being subjected to electrolytic oxidation and reduction is an industrial waste effluent.
