Micellar colorimetric determination of iron, cobalt, nickel and copper using 1-nitroso-2-naphthol

1-Nitroso-2-naphthol, an excellent color-forming chelating agent, combines to Fe(III), Co(II), Ni(II), Cu(II) and so on to form slightly soluble complexes in aqueous solution. To determine these metal ions, a tedious and time consuming separation technique, such as liquid–liquid extraction, has ofte...
