Abstract: | Dichloro - dimethyl hydantoin is white powder or granules containing 64 .45 % avail able chlorine. The killing rates of Escherichia coli exposed in the solution containing available chlorine 50 mg/Lfor 2 min , Staphylococcus aureusexposed to the solution containing available chlorine 100 mg/Lfor 10 min and sporesof Bacillussubtilis var. niger exposedto thesolution containing available chlorine 1000 mg/Lfor 20 min were > 99 .9 % . The solution containing available chlorine1000 mg/Lwith a15 min contacttimecould destroy completelytheantigenici ty of HBsAg .The available chlorine contentin its powder decreased by 6 .50 % after storing at 54 ℃for 14 days.Its solution containing available chlorine 1500 mg/Lhad slightly to heavily corrosive effecton stainlesssteel,aluminum ,copperand carbon steel. |
