Analytical Application of 2-Hydroxy-4-Isobutoxy Acetophenone Oxime for the Determination of Cobalt

Authors(1) :-Dr. J. R. Shukla

2-Hydroxy-4-isobutoxy acetophenone oxime(HIBAO) has been used for the spectrophotometric determination for Co(II) at pH range 6 to 10 in chloroform medium. Job’s method for continuous variation, Yoe and Jones’ mole ratio method, the slope ratio method show metal ligand ratio in complex to be 1:2. The stability constant of the complex is found to be 5.73 X109. The brown coloured complex obeys Beer’s law in the concentration range 5.89 g/ml to 47.14 g/ml for Co(II) ion, while the optimum concentration range from Ringbom plot is found to be 11.79 to 41.25 ppm. The photometric sensitivity and molar absorptivity at the 600nm are found to be 0.055 µg/cm2 and 1074 mol-1cm-1 respectively. The standard free energy of formation of complex is -13.52 kcal/mole at 30oC. The complex is stable for 48 hrs. The reagent has also been found to give quite satisfactory results for Co(II) present in alloy like brass, bronze and synthetic mixtures. The antimicrobial Activity of HIBAO and Co-HIBAO complex have also been checked.
