Abstract: The invention is a method and apparatus using high cerium concentration in the anolyte of an electrochemical cell to oxidize organic materials. The method and apparatus further use an ultrasonic mixer to enhance the oxidation rate of the organic material in the electrochemical cell. A reaction vessel provides an advantage of independent reaction temperature control and electrochemical cell temperature control. A separate or independent reaction vessel may be used without an ultrasonic mixer to oxidize gaseous phase organic materials.

Abstract: An electrochemical cell (20) which is effectively leakproof and can be incorporated into an easily serviceable cell pack (80). Within the cell are a plurality of parallel electrode plates (44, 46, 56) which act as anode and cathode reaction surfaces for processing chemicals. The electrochemical cell housing (33) is preferably formed of durable plastic with all fluid inlets (36, 38) and outlets (40, 42) on its upper face (30). One or more input manifolds (48, 50) are provided to route process chemicals to the bottom of the cell and then distribute them upward across the electrode plates. The housing is formed as a one-piece, monolithic structure with an opening left on top for fitting the top face. At the end of cell assembly, the top face is attached to the remainder of the cell housing so as to form a sealed cell.
