Determination of Nickel and Manganese by Kinetic H-Point Standard Addition Method Open
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) …
