Corrosion of Metal in Chlorine Dioxide Disinfection Solution

The corrosion of A3 steel,copper,aluminum,stainless steel in 50 mg/L,100 mg/L,200 mg/L and 400 mg/L chlorine dioxide disinfection solution at room temperature was studied by the method of static weight-loss.The results showed that when the concentration of chlorine dioxide disinfection solution was 200 mg/L,the corrosion degree of aluminum was mild and that of copper was moderate;when the concentration of chlorine dioxide was 400 mg/L,the corrosion degree of A3 steel was severe and that of stainless steel was mild.The possible corrosion reason was analyzed.
