- The synthesis of 1-(2-pyridylazo)-2,7-dihydroxynaphthalene (2,7-PADN) and the electroanalytical characteristics of its metal complexes are reported. In pH 9.80 buffer solution the complexes of copper, nickel, lead, cobalt and cadmium with 2,7-PADN give sensitive adsorption polarographic waves at −0.35, −0.45, −0.49, −0.60 and −0.67 V, respectively, which can be used to determine trace amounts of these elements, the detection limits being 8.0, 5.0, 2.5, 0.5 and 5.0 nM, respectively.
