摘　　要：采用静态失重法试验了常温下A3钢、铜、铝、不锈钢在50mg/L、100mg/L、200mg/L和400mg/L的二氧化氯溶液中的腐蚀情况。结果表明,在200mg/L二氧化碳消毒体系下,铝为轻度腐蚀,铜为中度腐蚀;在400mg/L二氧化氯消毒体系下,A3钢为重度腐蚀,不锈钢为轻度腐蚀。并分析了腐蚀的原因,为二氧化氯的广泛应用提供基础。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.
