ABSTRACT
2-Hydroxy-3-methoxy Benzaldehyde Oxime (2H3MBO) as a photometric reagent for the extractive spectrophotometric determination of Molybdenum (VI) is presented in this paper. The reagent 2H3MBO gave instantaneous and stable peacock green with Molybdenum (VI) in the pH range 1.2 to 2.4. The system obeys Beer’s law in the range in the concentration range of 1.0 - 25.0μg/mL at 390 nm. The Limit of Detection (LOD) is calculated by using standard deviation of blank solution at confidence limit 98.3%, which is found to be 0.375μg/mL. The stoichiometry of the complex is established as 1:1 (M:L) by Job’s method of continuous variation and confirmed by mole ratio method. The standard deviation and the coefficient of
variance are presented. The results of the prescribed procedure applied for the determination of the micro amounts of Mo (VI) in standard steel samples, alloys, pharmaceutical and synthetic samples are presented.
