Objective To establish a method for analysis of Cyanide in biological samples by Iso-nicotinic Acid-pyrazdone color class method.Methods The Cyanide was extracted by steam distillation. In the buffer solution at pH6.8-7.0, the Cyanide reacts with chloramine-t forming Chlorocyanogen, and then the Chlorocyanogen reacts with Iso-nicotinic and Acid-pyrazdone to form a stable blue complex.Results The content range of Cyanide was estimate by compared the color class of standards and samples.Conclusion This method is simple and accurate and can used for analysis of Cyanide in biological samples.
