Micro electrolysis of iron carbon
Iron carbon microelectrolysis mainly utilizes the difference in electronegativity between iron and carbon to undergo redox reactions (electrochemical corrosion) in wastewater, forming countless tiny primary cells. Iron serves as the anode to lose electrons, while carbon serves as the cathode to give electrons to cations in water. The electrode process is as follows:
Anodic reaction:
Fe-2e→Fe2+ E0(Fe2+/Fe)=-0.44V
Cathodic reaction:
2H++2e→H2↑ E0(H+/H2)=0.00V
When there is oxygen present
O2+4H++4e→2H2O E0(O2)=1.23V
O2+2H2O+4e→4OH- E0(O2/OH-)=0.40V
Iron releases electrons during wastewater treatment to generate new ecological Fe2+, which has an oxidation-reduction effect and can undergo oxidation-reduction reactions with many components in wastewater

(1) Reduce hexavalent chromium to trivalent chromium and separate it by precipitation;
(2) Reduce heavy metals (such as mercury and copper ions) to elemental form, precipitate and separate;
(3) Separate inorganic anions (such as S2- ions that form insoluble substances with iron) by precipitation;
(4) Reduce nitro (benzene) to amino (aniline), reduce biological toxicity, and improve biodegradability;
(5) Oxidation reduction of conjugated colored groups (such as azo colored groups or chromophore groups) to degrade and decolorize the chromophore;
(6) Long chain or cyclic polymer organic compounds undergo ring opening and chain breaking degradation, improving the biodegradability of wastewater. The generated Fe2+further oxidizes with O2 in the air to Fe3+, and the pH of the wastewater rises to 8-9 after reaction. The hydroxide formed by Fe3+is a good flocculant. The newly formed iron hydroxide colloid has a strong adsorption flocculation effect, and its adsorption capacity is much higher than that of flocculants obtained by hydrolysis with external chemical agents; Suspended solids, toxic substances, heavy metal ions, and organic macromolecules dispersed in water pollution can be separated by adsorption flocculation and precipitation.
The working principle of microelectrolysis process is the result of the combined action of electrochemical oxidation-reduction reaction, chemical reaction, physical and chemical adsorption, and flocculation precipitation.
