Abstract :A rapid and reliable method for estinıation of copper and vanadium based on its precipitation by ferrocyanide, and the unreacted ferrocyanide is oxidized with 2% iodine solution dissolved in acetic acid to ferricyanide, and formation of iodide ions. The iodide ions produced are titra- ted with mercuric nitrate using silver amalgam as the indicator electrode and calomel as the other half celi. This method is applicable to the accurate determination of copper insert ignore into journalissuearticles values(II); and va¬nadium insert ignore into journalissuearticles values(IV); alone or in its mixtures.
