In paper electrophoresis using 0.05N sodium carbonate or 1% sodium hydrogen carbonate solution as the electrolytic solution, sodium pentacyanoammineferroate, pentacyanoaquoferroate, and the colored pentacyano-iron complex salts migrate as anions, and this process can be utilized for separatory identification and estimation of the original organic compounds in the colored pentacyano-iron complex salts formed by the reaction of sodium pentacyanoammineferroate and organic compounds. Similar complex salts formed by reaction of sodium nitroprusside and organic compounds are unstable and cannot be separatory determined by this paper electrophoretic method. The migration value of a sample is inversely proportional to the concentration of electrolytic solution at a constant voltage gradient, while the value is proportional to voltage gradient and current density under constant concentration.
