Temporal Stability of Oxidizers: A Preliminary Survey of Aqueous Solutions.
Abstract
Aqueous solutions (nominal 0.1N each anion) of various hypochlorite salts (sodium, calcium, lithium) and peroxygen compounds (sodium perborate, sodium persulfate, hydrogen peroxide and magnesium monoperoxyphthalate) have been examined for long-term stability. Lithium hypochlorite solutions in distilled water were stable (i.e., maintained oxidizer capacity) for over 14 days, whereas calcium hypochlorite exhibited oxidizer capacity for only some 5 days. The peroxygen compound solutions displayed stabilities ranging from 2 days (sodium perborate) to approximately 10 days (sodium persulfate and hydrogen peroxide). These solution stability data, monitored by iodometric titrimetry, provide information on how long potential decontamination materials may remain stable in storage as dry, bulk substances. Long stability in solution argues for long stability in bulk form. Stability in storage would be a desirable characteristic, should one or more of the candidates examined prove efficacious for decontamination applications. Originator furnished key words include: Oxidizer; Water; Stability; Titration; Iodometry.
