The triiodide form of an anion-exchange resin an |
|
effective antimicrobial in water is claimer to attenuate |
|
infectivity of airborne microorganisms. However, attempts |
|
to evaluate the effect of passage through a filter medium |
|
containing the triiodide resin were impeded by reactions |
|
of iodine with proteins during collection and with water |
|
during analysis. Aerosols of MS2 coli phage were passed |
|
through control P100 and iodinated HEPA media, collected |
|
in plastic bags, incubated for 0 10 min, collected in an |
|
impinger containing thiosulfate to consume unreacted |
|
iodine, plated and enumerated. Comparison of viable |
|
counts demonstrated antimicrobial activity with an |
|
apparent half-life in tens of seconds. Antimicrobial |
|
effectiveness increased with relative humidity. |
|
Absorption of iodine by the bags eliminated reaction with |
|
free iodine as a contributing mechanism. The iodinated |
|
medium appears to have possible use in collective, but |
|
likely not individual, protection. |
