The Dial-A-Decon solution chemistry gap testing, documented in this report, was performed to fill some of the higher priority data gaps identified by the Solution Chemistries for Point-of-Use Decontamination Formulation report published by Noblis, Inc. Falls Church, VA in April 2009 for the Defense Threat Reduction Agency. The Noblis report included an assessment of the science that could be used in point-of-use formulation of decontaminants effective against the chemical warfare agents, sulfur mustard HD, VX, and G agents, and the endospore biological agent, Bacillus anthracis. As part of their task, Noblis identified and prioritized data gaps from the available literature. The data gaps tested and reported here include the influence of solution pH on the reaction rate of VX with peracetic acid, peroxoborate, peracetylborate, peroxomonocarbonate, and percarbonate the effect of solvent polarity on the reaction rate for VX and GD in solutions of peroxoborate, peracetic acid, and peroxomonosulfate the influence of surfactant type on spore removal the relationship between the surfactant hydrophilic lipophilic balance number and its ability to emulsify HD and emulsion experiments to determine the concentration of HP, emulsified as a function of the surfactant concentration.
