Study on the corrosiveness of peroxide disinfectants to metals at commonly used concentration
Objective To study the corrosion of metals by chlorine dioxide,hydrogen peroxide,and peracetic acid.Methods Four kinds of chlorine dioxide,three kinds of hydrogen peroxide and three kinds of peracetic acid products were selected to study their corrosiveness to five kinds of metals of carbon steel,aluminum,copper,stainless steel and zinc sheet,and the corrosion rate was calculated.Results The liquid formulation of 300 mg/L chlorine dioxide exhibited severe corrosion on carbon steel sheets,copper sheets,aluminum sheets,and zinc sheets;Under the condition of 500 mg/L,chlorine dioxide solution still had little corrosion on stainless steel sheets.3%hydrogen peroxide solution had little corrosion on carbon steel and stainless steel sheets,mild corrosion on copper and aluminum sheets,and severe corrosion on zinc sheets.1.0 g/L peroxyacetic acid liquid preparation caused severe corrosion to carbon steel sheets,copper sheets,and zinc sheets,moderate corrosion to aluminum sheets,and minimal corrosion to stainless steel sheets.Conclusion Except for stainless steel,three types of peroxide disinfectants have corrosiveness to other four metals,hydrogen peroxide has lower corrosiveness,followed by chlorine dioxide,and peroxyacetic acid has the severest corrosivenes.
