Using analytical reagent N -(o -methoxy benzaldehyde) 2-aminophenol (NOMBAP) a feasible, sensitive and rapid spectrophotometric method has been developed for the determination of Mn (II). NOMBAP has been synthesized and characterized by elemental analysis. NOMBAP extracts Mn (II) quantitatively (99.45%) into n-Butyl alcohol from an aqueous solution of pH range 9.4 -10.7. An intense peak at 480 nm (λ max) was observed in the extract of n-Butyl alcohol. Beer's law is obeyed over the concentration range 0.5 -9.0 µg/mL for Mn (II). The molar absorptivity and Sandell's sensitivity for Mn -NOMBAP system is 62381.9 L mole -1 cm -1 and 0.0082μg cm -2 respectively. Job's Continuous Variation and Mole Ratio Method confirms that the extracted (Mn:NOMBAP) complex has composition 1:2. The average of 10 determination of 5 µg of Mn (II) in 10 cm 3 solutions was 4.999 µg, which is varied between 4.995 and 5.003 at 95% confidence limit and standard deviation is ±0.006. Interference by various ions has been studied. The proposed method is rapid, sensitive, reproducible and accurate and it has been satisfactory applied for determination of Manganese in Ore and Alloy samples)
