A highly sensitive extraction-photometric method for nickel with dithizone and phenanthroline.
Addition of phenanthroline to nickel dithizonate in chloroform results in a mixed ligand complex, NiDz(2)phen, the high molar absorptivity of which (49.1 x 10(3)) results in a colorimetric estimation of nickel that is significantly more sensitive than any other method.
