Abstract
Contemplated devices and methods include an electrolytic cell having a cathode and a carbon felt anode, wherein the carbon felt anode is configured as a flow-through anode for an aqueous solution in which a contaminant is dissolved or dispersed. The cell is operated at a current density that promotes formation of oxidizing species in neutral pH to thus destroy the contaminant and at a flow rate sufficient to prevent oxidative damage of the carbon felt.
Claims17
A method of treating an aqueous solution, comprising:
- providing an electrolytic cell having an anode in an anode compartment, a cathode in a cathode compartment, and a diaphragm separating the anode compartment from the cathode compartment to thereby fluidly isolate the anode compartment from the cathode compartment;
- wherein the anode comprises a carbon felt that is conductively coupled to an electrical connector such that a flow path is formed to allow flow of the aqueous solution through the carbon felt;
- moving the aqueous solution through the anode compartment such that substantially the entire solution passes through the carbon felt from one side to another side;
- and
- operating the electrolytic cell at a current density effective to generate oxidative species from the aqueous solution in an amount sufficient to oxidize a contaminant in the aqueous solution.
