5-[(p-Methyl-phenyl)azo]-8-aminoquinoline as a new reagent for trace determination of nickel by adsorptive cathodic stripping voltammetry.
The synthesis of p-MPAQ and the electroanalytical chemical properties of the nickel(II)-p-MPAQ complex are reported in this paper. A sensitive adsorptive cathodic stripping procedure for trace nickel determination was developed. For a 3-min preconcentration time the detection limit is 3.0 x 10(-11)M.
