SYSTEM FOR PERFORMED THE FENTON’S REACTION BY A PHOTO-ELECTROCHEMICAL-CATALYTIC EFFECT, METHOD FOR OBTAINING FREE RADICALS (°OH) AND REGENERATION OF SUPPORTED IRON (FE(II)).

摘要

The present invention refers to a system to conduct the Fenton’s reaction by a photo-electro-chemical-catalytic effect and method for obtaining free radicals (°OH) and regenerating supported iron (Fe(II)), where the residual iron intends to comply with the standard established for the presence of said metal in potable water; in such a manner, the method provides the generation of free radicals °(OH) required for the degradation of organic matter like pesticides, insecticides, dyes and further harmful compounds that are dissolved in residual water, where the amount of free radicals (°OH) be higher in the same dissolution volume, so as to accelerate the degradation speed of the organic matter as well as the discoloration speed and the removal of the total organic carbon; said free radicals (°OH) are generated by hydrogen peroxide (H2O2) generated in situ in a Fenton’s reactor, which uses supported iron in ionic exchange resins of low desorption level, as well as photo assisted processes and an anode coated with a nano-crystalline semiconductor.
