Wells-Dawson hetero-metal substituted polyoxometalates (POMs) are effective in aqueous decontamination solutions against organic CWA simulants.  Rapid oxidation of the organophosphate simulant Demeton-S is achieved with aqueous solutions of hydrogen peroxide containing Ni(II) and Zr(IV) substituted polyoxometalates. Moving beyond polyoxometalate hydrogen peroxide solution base decontamination, tungsten peroxo species have been synthesized and utilized as both solid phase and solution based decontamination agents.  Facile synthetic schemes for both polyoxometalates and tungsten peroxo species make them ideal for utilization on larger scales.  Spectroscopic analysis of the synthesized materials matched that presented in the literature, confirming synthesis.  Simulant challenges for the synthetic materials in both solution and as solids were performed in order to assess their decontamination capacity.  Chromatography coupled with mass spectroscopy was utilized for the analysis of the reaction progress and for confirmation of byproduct formation from challenge experiments.
