Qualitative Analysis for Trace Amounts of Organocompounds Derived from Constitutional Materials of Electrolytic Compartments During Generation of an Acidic Electrolyzed Water

Abstract

The solution produced in the anolyte compartment by the electrolysis of a dilute NaCl solution, ie., acidic electrolyzed water was analyzed by a gas chromatograph/mass spectrometer (GC/MS). As a result, organochlorinated compounds that are derived from constitutional materials of electrolytic compartments, and silicone compounds originated from O-ring of electrolytic compartments were detected. We examined the surfaces of ABS resin and a diaphragm, which were immersed in acidic electrolyzed water for 4 weeks, by scanning electron microscopy, slight changes of the surfaces were observed. It is likely that acidic electrolyzed water that contains free chlorine deteriorates constitutional materials of electrolytic compartments.
