Aluminum, iron(II), copper, and molybdenum 8-quinolinol complexes, chromium (II) and manganese 8-hydroxyquinaldine complexes and nickel dimethylglyoxime complex can be quantitatively extracted into chloroform from large volumes of aqueous phases adjusted to an approriate pH for each metal. These metals can be determined by measuring the absorbance of the organic phases containing their complexes at an appropriate wavelength for each metal. By the proposed method, quantities exceeding 3p.p.b. of aluminum, chromium, and manganese, and 5p.p.b. of copper, iron, molybdenum and nickel can be determined when a 500 ml sample of water is available.
