The effectiveness of the disinfectant preparations Persteril, Pedox and Peroxid Aktiv K, based on persteril, was tested under laboratory conditions on bacterial strains E.coli, S.aureus. Testing was carried out by a suspension test, using concentrations of the active ingredient from 0.01 to 2.0% and exposure time 5, 30 and 60 minutes, and by a dilution test at concentrations from 0.02 and 2.0 %. The results were compared with those obtained for Chloramin B, based on active chlorine. Good devitalisation effects on tested bacteria were observed for all three preparations. Persteril provided the best results in both the tests and was followed by Pedox. The effectiveness of Peroxid Aktiv K was close to that of Chloramin B but required longer exposure time.
