Various potential decontamination agents were examined as solids and in aqueous solutions for long term stability at high temperatures. The following oxidizers were assayed iodometrically the hypochlorite salts of calcium and lithium, sodium dischloroisocyanurate PACE and the preoxygen compounds sodium perborate, sodium peroxydisulfate, sodium percarbonate, and magnesium monoperoxyphthalate H-48. The inorganic peroxide solids and the solid sodium dischloroisoyanurate were stable at 80 C, while the organic peroxide solids and the hypochlorite salts deteriorated markedly within 72 hours. In freshwater solutions of 0.01 N or less, the inorganic hypochlorite and peroxide salts decomposed slowly at 60 c. Conversely, the sodium dischloroisocyanurate, magnesium monoperoxyphthalate, and sodium percarbonate solutions exhibited near complete decomposition in 24 hours.
