摘　　要：目的研究稳定型含氯消毒剂存放过程中的稳定性。方法在半开放与封闭条件下，对有效氯浓度介于60～15000mg／L的稳定型含氯消毒剂进行长达590d的保存实验，并对其主要指标与消毒性能进行监测。结果保存条件与有效氯浓度对稳定型含氯消毒剂的稳定性有明显影响，较高含量的有效氯浓度与封闭保存条件可获得较长的保存期；在保存过程中稳定性含氯消毒剂的消毒能力略降，主要与其有效氯的衰减有关。结论在封闭保存条件下，稳定型含氯消毒剂的保存期可长达1年，并保持较强的消毒能力，具有实际使用价值。Objective To evaluate the stability of a stable chlorine disinfectant during storage. Methods A 590 days＇ storage experiment was carried out for the stable chlorine disinfectant samples with effective chlorine contents ranging from 60 to 15 000 mg/L to investigate the changes of their main parameters and disinfection property. Results The storage conditions and effective chlorine contents of the stable chlorine disinfectant had an obvious effect on its stability. The higher contents of effective chlorine as well as the closed storage conditions could get a longer preservation period for the stable chlorine disinfectant. During storage, the disinfection property of the stable chlorine disinfectant decreased gradually, which was believed to be related to the decrease of its effective chlorine content. Conclusion The stable chlorine disinfectant can get one year＇ storage period under a closed condition. After long period of storage, it still keeps a stronger disinfection property and has a practice usage.
