Estimating the term…
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.
A dry solid composition for generating chlorine dioxide, the composition comprising a chlorine dioxide precursor and hydroxymethanesulfinic acid monosodium salt dihydrate (HMS), wherein the chlorine dioxide precursor and the HMS are physically arranged such that contacting the chlorine dioxide precursor, the HMS, or both with a fluid containing water produces the chlorine dioxide.
A method for generating chlorine dioxide, the method comprising:
A method of making a dry solid composition, the method comprising physically arranging a chlorine dioxide precursor and hydroxymethanesulfinic acid monosodium salt dihydrate (HMS) in an anhydrous environment such that contacting the chlorine dioxide, the HMS, or both with a fluid containing water produces chlorine dioxide.
