Catalytic Oxidation of Mustard Simulants in Basic Solution
Abstract
The results of the current project to date show various approaches that can be used to improve the efficiency of bicarbonate-activated hydrogen peroxide for CWA and BWA destruction. Kinetic and spectroscopic results support the formation of peroxymonocarbonate ion (HCO4-) as the oxidant in the catalytic reactions. Variation of bicarbonate source and the cosolvent can allow optimization of substrate solubility and oxidation rates for applications in chemical warfare agent decontamination, Use of surfactants and microemulsions in place of non-aqueous cosolvents has proven to be effective for mustard simulants. Surfactant-catalyst formulations have been developed that enhance oxidation reaction rates up to 20-fold or more over usual cosolvent-based BAP formulations. Biochemically-relevant oxidations have been studied in view of the possible combination of enzymatic and chemical decontamination approaches as well as the potential of BAP for BWA applications. Recent work has determined the enhancement of peroxide biocidal activity in the BAP system via direct studies of bacterial culture survival rates under various treatments.
