ABSTRACT
A simple, rapid, sensitive and selective method is developed for the spectrophotometric determination of manganese (II). The reagent, 2-Hydroxy-3-methoxy benzaldehyde thiosemicarbazone (HMBATSC) gives greenish brown colored water soluble complex in aqueous DMF medium with manganese (II). The greenish brown colored Mn (II) – HMBATSC complex shows maximum absorbance at 435 nm in the pH range 9.0 – 10.0. However, at this wavelength, the reagent shows considerable absorbance. At 445 nm, the complex shows large absorbance while the reagent blank shows negligible absorbance. Hence, the analytical studies are carried out at 445 nm at pH 9.5. The molar absorptivity and Sandell’s sensitivity are 1.96 x104 l mol-1 cm-1 and 0.028 μg cm-2 respectively. Beer’s law is obeyed by Mn (II) in the range 0.1373–2.746 μg ml-1. The composition (M:L) of the complex has 1:1 and stability constant of the complex is calculated as 1.22 x107. The effect of various diverse ions also incorporated. A first order derivative spectrophotometry has also been proposed for the determination of Mn (II). The present method is applied for the determination of manganese in tap water, milk, alloy steels and plant samples.
