Abstract
A method of electrolytically decomposing the ionizable chemical compounds that consists of introducing an aqueous solution of said ionizable chemical compound into an electrolytic cell provided with an anode compartment and a cathode compartment that are separated from each other by a homogeneous cationic active membrane formed from a hydrolyzed copolymer of tetrafluoroethylene and a sulfonated perfluorvinyl ether of the formula: FSO2CF2CF2OCF (CF3) CF2OCF = CF2 said copolymer having an equivalent weight of approximately 900 to 1600, establishing a decomposition voltage of about 2.3 to 5 volts through the electrodes arranged in each of said compartments while maintaining an anodic current density comprised between approximately 0, 5 and 4 amps/inch2 (0.0077 to 0.620 amp/cm2) and recovering from said cathode compartment a product containing less than about 1% by weight of said ionizable chemical compound.
