ABSTRACT:

2-Hydroxy-4-isopropoxyacetophenone oxime [HIPAO] has been used for gravimetric and spectrophotometric determination of Mn(Il) at pH-9.0 Job's method of continuous variation and Yoe and Jones mole ratio method show metal ligand ratio in the complex to be 1:1, The molar absorptivity of complex at 440 nm is found to be 3450.0 lit. mole-1 cm-1 and Sandell's sensitivity found to be 0.015 ug/cm2. The stability constant determined spectrophotometrically is found to be 1.15x106 and Gibbs free energy change for complex formation reaction is calculated to be - 8.39 K.cal / mole. The Beer's law is obeyed upto 4.4 ppm of Mn(Il) ion at 440 nm.
