過酸化水素による銅及び第一鉄の微量定性反應

抄録

By the addition of 20-30% H₂O₂ to a solution of metal ions containing a few drops of 1% aqueous solution of aniline at pH 4.4-6.2, copper and ferrous ions are respectively detected by the resultant color. Coloration of Ti and Ce can be masked by NaF, copper by glycine, and Fe^.. by its oxidation to Fe^.... Limit of detection is 0.04 γ of copper and 0.2 γ of Fe^...
