Abstract: In a pH 6.8 buffer solution containing 0. 0011% Triton X-100 the complex of the nickel( Ⅱ) with p-MPAQ shows a sensitive adsorptive complex wave at -0. 93 V, which can be used to determine trace amounts of nickel down to 5. 0×10-9mol/L. The proposed method has been applied to the determination of trace amounts of the nickel in aluminium alloy samples.

Key words: p-MPAQ, Polarography, Nickel assay
