[Determination of cyanide in whole blood by completely differential spectrophotometry].
This paper introduced a method for the determination of cyanide in whole blood by completely differential spectrophotometry with pyridine-pyrazolone method after stabilization by addition of silver sulfate and separation by distillation. The analytical results showed a precision 5.4% (n = 6) for the determination of 0.068 microgram.ml-1 CN- in whole blood. The average recovery was 97.4%. This method was successfully used for the determination of cyanide in whole blood of non-smokers and smokers.
