Progress toward Developing a Monitoring Method for Hydrogen Cyanide in Air

摘要

The development of an analytical procedure for measuring free cyanide, the various solid and liquid sorbents tested, and the instability problems encountered during research to establish a monitoring method for hydrogen-cyanide (74908) (HCN) in air are described. The original goals of the project were the development of improved sampling and analytical methods for hydrogen-fluoride (7664393), HCN, and particulate cyanides by replacing liquid impinger samplers with solid sorbent samplers and using an ion chromatographic analytical technique.
