Abstract
A composition and method for chlorine dioxide production through reaction-diffusion chemistry that facilitates the in situ generation of chlorine dioxide, wherein a dry solid composition of hydroxymethanesulfinic acid monosodium salt dihydrate (abbreviated HMS) and a chlorine dioxide precursor are activated via the addition or absorption of water to produce chlorine dioxide. The dry solid chemical composition comprises dry, safe, transportable reagents that integrate with polymeric materials such as packaging and superabsorbent and stimuli-responsive hydrogel polymers to combine with water to produce chlorine dioxide.
