Quantitative Analysis of Prussic Acid by "Micro-Diffusion Analsis." II Determination of Prussic Acid in Human Blood

미량확산분석법에 의한 청산의 정량법 (제2보) 혈액중(CN-Met Hb)청산의 정량

Another application of the new quantitative analytical method of prussic acid by "Microdiffusion analysis" for the determination of prussic acid in human blood was studied. The blood containing potassium cyanide was dropped in outer room of unit, and then N-sulfuric acid was added. The liberated HCN gas was absorbed into nickel sulfate solution of inner room, afterward, absorbed prussic acid was determined with EDTA by residual titration. The result was coincided with the result of Liebig Denigs' method at ordinary temperature.
