H-point standard addition method (HPSAM) was applied to kinetic data for simultaneous determination of Ni(II) and Mn(II). The method is based on the difference between rate of complexation of 1-(2-pyridylazo)-2-naphthol (PAN) with Ni(II) and Mn(II) at pH 7.5 in Triton X-100 micellar media. Ni(II) and Mn(II) can be determined simultaneously in the concentration range 0.084-0.734 and 0.055-0.366 μg mL-1, respectively. The proposed method has successfully been applied for simultaneous determination of Ni(II) and Mn(II) in synthetic samples, spiked water samples, alloys and food products.
