The effectiveness of chlorine dioxide gas in portable personal disinfectants to inhibit bacterial growth

Disinfectants, especially air disinfectants, are a necessity to prevent the potential spread of pathogens (bacteria and viruses) in the pandemic era and minimize the spread of the SARS-CoV-2 virus. Some of the commercial disinfectant products that are often used generally contain chlorine dioxide (ClO2) gas. This study tested the effectiveness of two different commercial disinfectants, a liquid stick disinfectant and a powder disinfection card, to carry out the disinfection of pathogenic bacteria in the environment or space. The isolated microorganisms are used as a medium to evaluate the effectiveness of both commercial products in killing pathogens. In the form of a liquid stick, ClO2 is more effective in disinfection rather than in the form of powder. The effectiveness of the liquid disinfectant in inhibiting the growth of pathogenic bacteria is influenced by the temperature and the area of the open space covered. Considering that the release from both disinfectants used is very small (,0.002 ppmv/h), it takes a small area to ensure that the disinfection process runs effectively.
