Abstract: The present invention provides for a composition, including: a sufficient first amount of a first active agent dispersion; where the first active agent dispersion has a pKa of 0.1-2.0, where the first active agent dispersion is selected from the group consisting of: an acid cation exchange resin, an acidic zeolite, an acidic clay, an organic acid, an inorganic acid, and any combination thereof, and where the first active agent dispersion includes a plurality of particles; where the plurality of particles has a median diameter of between 0.5-1000 micrometers; and a sufficient second amount of at least one chlorite salt dispersion; where, when the composition is contacted with an aqueous liquid, the sufficient first amount of the first active agent dispersion and the sufficient second amount of the at least one chlorite salt dispersion results in a generation of chlorine dioxide radicals.
