INACTIVATION OF BACTERIA WITH SMAC – A STABLE SOLUTION OF CHLORINE DIOXIDE IN WATER
Chlorine dioxide is a highly effective oxidising agent with powerful deodorising and bleaching properties. Its action on pathogenic micro-organisms is stronger than that of chlorine. A major drawback has, until now, been that chlorine dioxide invariably must be produced on the spot by reacting chlorine or hydrochloric acid in solution with sodium chlorite. A stable solution of 1.5 g per litre of chlorine dioxide in water is now available under the trade name SCAN MED Aqua Care (SMAC), produced by SCAN MED Industries Sweden AB. We have investigated the disinfecting power of this product using the membrane filter method with endo agar to investigate the inactivation over time, 30, 60 and 90 seconds, of Escherichia coli at bacterial concentrations from 102 up to 108 bacteria per ml water with 0.5, 1 or 2 mg chlorine dioxide (SMAC) per litre. “Complete abstract not presented.”
