Objective To develop a homogeneous solid
preparation of chlorine dioxide for battlefield use. Methods Water soluble passivator
was utilized to encapsulate the powders of sodium chlorite and acid activator with micro encapsulation technique,and thus a homogeneously powdered
preparation was formed,which would release effective free chlorine dioxide when dissolved in water.The properties of the regent were tested according to the Disinfecting Technology Standard.And also were tested its applications to drinking water,dinner set,environment and fighting against biological warfare agents. Results This research showed that the homogeneously micro encapsulated chlorine dioxide solution had a powerful casualty effect on Escherichia coli,Staphylococcus aureus,Bacillus subtilis var.nigerspores,Bacillus Anthracis and HbsAg.The proper concentrations of chlorine dioxide in the solution were found to be 1 mg/L for drinking water disinfection,50 mg/L for dinner sets disinfection and 200 mg/L for environmental disinfection,respectively.The micro encapsulated
homogeneous powder of chlorine dioxide was characterized by high stability,weak corrosiveness,weak stimulation and non poisoning. Conclusions The preparation retains all the advantages of the chlorine dioxide,and it is easy to be carried about,to be stored up and to be used.It was greatly potential to battlefield usage.
