A Rapid Spectrophotometric Blood Cyanide Determination Applicable to Emergency Toxicology

Abstract

Cyanide determination in whole blood can be performed by epectrophotometry after using diffusion coupled with coloration by hydroxocobalamin in a Conway dish. The technique may be accelerated by the use of a heating sheet at 45°C. The method proved to be specific, sensitive, and fast, thus permitting measurements in emergency situations.
