ABSTRACT:
A simple spectrophotometric method has been developed for the determination of Osmium (IV) by using Schiff base 2-[(2-hydroxyphenylimino) methyl]-4-nitrophenol [HPIMNP]. HPIMNP extracts Os (IV) quantitatively (99.94%) into iso - amyl alcohol from an aqueous solution of pH range 0.0 - 2.0. The iso - amyl alcohol extracts show maximum absorption at 545 nm (? max). Beer’s Law is obeyed over the Os (IV) concentration range of 1.5 to 24.0 µg/ ml. The Molar absorptivity and Sandell’s sensitivity for Os – HPIMNP system is 3700.00L mole-1 cm-1 and 0.051µg.cm-2 respectively. The composition of extracted species is found to be 1: 3 [Os - HPIMNP] by Job’s continuous variation and Mole - ratio method. 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 Osmium (IV) in Synthetic mixture samples.
