Practical methods for the quantitative measurement of cyanide and thiocyanate content in small biological samples are presented. The basis of the procedures is electrochemical determination of CN- with a silver rotating disk electrode at 90 mV, relative to the Ag/AgCl reference electrode, or with a dropping mercury electrode in differential pulse mode at -240 mV. Thiocyanate is oxidized to CN- with permanganate under controlled conditions prior to its analysis. Endogenous cyanide and cyanide from SCN- oxidation are recovered, separately, by volatilization and trapping. Emphasis is placed on careful handling of specimens prior to analysis. Precautions include a provision for sequestering cyanide in storage, the use of an antioxidant, and an avoidance of the spontaneous sulfide formation from proteins that occurs in even mildly alkaline solutions.
