[Study on stable unified disinfectant capable of releasing chlorine dioxide]

Chlorine dioxide is a new type of forceful disinfectant, but it cannot be stored and transported as a gas and is very toxic. In this paper, a stable unified disinfectant capable of releasing chlorine dioxoide was introduced. This disinfectant was stable in dry state and could produce chlorine dioxide when it contacted with water. Its solution containing 3.3 mg.L-1 chlorine dioxide could kill 100% of B. subtilis var. niger spores after exposure for 5 minutes. Its solution containing 434 mg.L-1 chlorine dioxide could destroy 100% of HBsAg after exposure for 30 minutes. The content of chlorine dioxide in this disinfectant powder decreased by about 12% following storage at 56 degrees C for 14 days. It was essentially non-corrosive to stainless steel and moderately corrosive to carbon steel.
