The influences of temperature

stirring and preservation state on the stability of electrolyzed oxidizing water (EOW) were investigated.Temperature

stirring and preservation state had prominent effect on the available chlorine content(ACC) of EOW

while they had no effect on the value of pH and reductant-oxidant potential (ORP).In open and lighted conditions

ACC decreased regularly.In closed and lighted conditions

ACC decreased slowly.In closed and dark conditions

ACC almost did not change.Stirring (100 r·min-1) makes ACC decrease quickly and the rate constant “k” increased by five times.When temperature was 50℃

ACC decreased by 46.09% in five minutes and the reaction activation energy was 76.76 kJ·mol-1.By studying the sterilizing effect of EOW with different ACC

it was found that ACC also had remarkable influence on the sterilizing effect。When ACC was more than 38 mg·L-1

the ratio of sterilization reached more than 99%; when ACC was 20.57 mg·L-1

the ratio of sterilization was 92.73%; when ACC was 6.82 mg·L-1

the ratio of sterilization was only 83.30%.To improve the sterilizing effect of EOW

the stability of EOW should be enhanced to keep a upper value of ACC.
