bottles under light or dark conditions at 20° C for 30 days. The pH, oxidation–reduction
potential (ORP), electrical conductivity (EC), available chlorine concentration (ACC),
dissolved oxygen (DO), and bactericidal efficiency of NEW and AEW were determined
during storage or before and after storage, respectively. The pH and EC of NEW and AEW
remained unchanged in storage. The ORP, ACC and DO of AEW decreased 22%, 100 …
