| 摘要 |
What is provided herein is a three-dimensional water disinfectant composition comprising the reaction product of a cross-linked, anti-microbial organosilicon quaternary ammonium salt and a macroporous cationic exchange resin. The cross-linked organosilicon quaternary ammonium salt suitably comprises about 2 to 60% by weight of the composition and the ion-exchange resin about 40 to 98% by weight of the composition. In a preferred form of the invention, the organosilicon compound constitutes about 20 to 40% by weight of the composition. Such compositions exhibit broad spectrum anti-bacteria activity including gram-negative activity, and are active algicidally in preventing the growth of algae in the water. The ion-exchange resin preferably is either a weak or strong cationic macroreticular ion-exchange resin. Methods of making such compositions also are described herein.
