If a nation or a terrorist organization produced biological agents, they are likely stored in a form of liquid concentrate. In the present study, four chemical reagents, hydrogen peroxide, sodium dichloroisocyanurate (NaDCC), Perasafe, and DF200, were investigated on their potentials as safe, efficient and eco-friendly decontaminants for biological agents. Escherichia coli, α-amylase, and bacteriophage T4 were used as surrogate strains for biological agents. Hydrogen peroxide and DF200 showed drawbacks of a rapid heat evolution upon neutralization and thick foam building up, respectively. Perasafe was effective against E. coli and T4, but it did not inactivate α-amylase while the others were able to inactivate all three types of the surrogates. NaDCC was the most suitable decontaminant for its effectiveness against all three types of surrogates at low concentrations and being able to be neutralized without aforementioned problems.
