Abstract

2-Hydroxy-4-isobutoxy acetophenone oxime (HIBAO) has been used for the spectrophotometric determination for V(v) at pH range 2 to 3 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 3.39 X108. The yellow coloured complex obeys Beer’s law in the concentration range 25.47 g/ml to 203.76 g/ml for V(v) ion, while the optimum concentration range from Ringbom plot is found to be 76.41 to 203.76 ppm. The photometric sensitivity and molar absorptivity at the 580nm are found to be 0.361 µg/cm2 and 161 mol-1cm-1 respectively. The standard free energy of formation of complex is -11.82 kcal/mole at 30oC. The complex is stable for 48 hrs. The reagent has also been found to give quite satisfactory results for V(v) present in alloy like brass, bronze and synthetic mixtures. The antimicrobial Activity of HIBAO and V-HIBAO complex have also been checked.
