Optimization and Validation of a Surface Wipe Method to Determine Cyanide and Cyanate: Application to the Emergency Destruction System

Abstract

The U.S. Army Product Manager for Non-Stockpile Chemical Materiel could deploy the Explosive Destruction System to neutralize materiel containing cyanide. A surface-sampling method was required to ensure operator safety and demonstrate the equipment was not contaminated. A surface wipe method for free cyanide and cyanate was successfully validated using collection protocols suitable for personnel wearing personal protective equipment in a contaminated environment. There were no significant differences in method performance for free cyanide or cyanate. Under the conditions evaluated, the overall average accuracy (spike recovery) values from the wipe material were 76.7%, with a 95% confidence interval of 75.7 to 77.6% and from a single wipe used on an impervious surface were 45.4 %, with a 95% confidence interval of 42.9 to 47.9%. The overall detection limits for the entire process was 0.13 mg free cyanide or 0.10 mg free cyanate per wipe. Validated collection, extraction, and analysis protocols are included in the report.
