摘　　要：稳定性二氧化氯产品质量差异大。选择三种稳定性二氧化氯产品,对四种水样进行消毒试验。研究表明,稳定性二氧化氯产品标准规定的ClO_2含量检测方法不能识别劣质产品;便携式余氯仪、二氧化氯仪检测结果的相关性很好;消毒后水样中ClO_2余量、ClO_2^-含量与产品投加量呈二次曲线关系,ClO_3^-含量与产品投加量则线性相关;使用劣质产品时,消毒副产物超标风险很大。Large differences exist in the level of quality of stable chlorine dioxide solution prod- ucts. Disinfection experiments were carried out for three types of products on four water samples. The results showed that the ClO2 detection method, as specified in Stable Chlorine Dioxide Solution （GB/T 20783 -2006）, could not identify poor products. Strong correlation was observed between results from the portable free chlorine meter and the chlorine dioxide test instrument. Both ClO2 residue and ClO2- concentration showed quadratic relationships with product dosage. While, the ClO3- content was linearly related to the product dosage. There was a high risk of excessive disinfection by-products when poor prod- ucts were used.
