[Virucidal efficacy of inorganic per-compounds].
Among 7 inorganic per-compounds tested potassium permanganate as 1% solution showed the greatest virucidal efficacy against poliovirus type I and reached a reduction rate of 4.1 after 30 sec exposure time. Potassium peroxomonosulfate produced a reduction rate of 5.6 after 5 min, whereas perchloric acid and sodium perborate needed 15 min and hydrogen peroxide 60 min to show a reduction of 10(4) of the infectivity level. Potassium peroxodisulfate and sodium perborate yielded a reduction rate of 0.9 and 1.3, respectively. With protein load a slight reduction of antiviral efficacy was observed, whereas with extended standing times only the reduction rate of sodium percarbonate was lowered from greater than or equal to 4.9 to 2.0 after 60 min exposure time.
