Abstract
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.
