Abstract

An electrochemical oxidation reactor was used for advanced treatment of cyclic volatile methylsiloxanes using stainless steel plates as anode and cathode electrode. Several key factors were studied to optimize the electrochemical oxidation process. During the electrochemical oxidation process, the removal efficiencies of D5 (decamethylcyclopentasiloxane) increased with the reaction time and applied current densities. At the optimal operating parameters including plate distance of 1.0 cm, electrode plate amounts of 4 pairs, current density of 20 mA/cm2 and reaction time of 30 min, the removal efficiencies of D4 (octamethylcyclotetrasiloxane), D5 (decamethylcyclopentasiloxane), and D6 (dodecamethylcyclohexasiloxane) can reach 100, 82.1, and 72.5 %, respectively.
