Decontamination
Performance for Chemical Agent Simulants
At Sandia
National Laboratories (SNL) we tested the decontamination
performance of the Sandia Decon Formulation for chemical agent
simulants. The chemical agent simulants used were diphenyl
chlorophosphate (simulant for G-agents), 2-chlorethyl phenylsulfide
(simulant for H-agents) and O-ethyl-S-ethyl Phenylphosphonothioate
(simulant for VX). Testing was done via solution tests (i.e.,
the agent was added to our decontamination solution) and surface
tests (i.e., the agent was placed on a surface which was then
exposed to our formulation). The half-lives for the decontamination
of these CW agent simulants were on the order of few minutes.
We utilized NMR studies to demonstrate that destruction of
the VX simulant occurred via exclusive cleavage of the P-S
bond. The absence of P-O bond cleavage is important since
such cleavage would potentially result in the formation of
a toxic byproduct. Our decontamination technology does not
generate such toxic or hazardous byproducts.
We confirmed
our chemical agent simulant test results by contracting with
a facility licensed to perform live agent testing. Live agent
test results for foam decontamination of paper with GD, VX,
and HD are depicted below. The half-lives for the decontamination
of these CW agents by the foam is on the order of 2 minutes
to 15 minutes.
Decontamination of paper
treated with chemical agent at 25mg/25 cm2. Foam
was applied on contaminated paper for a given duration. Residual
simulant on the paper and in the foam were determined by GC
and added to determine total unreacted agent.
