Abstract

2-Hydroxy-4-isobutoxy acetophenone oxime(HIBAO) has been used for the spectrophotometric determination for Ni(II) at pH range 8 to 9 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 6.31 X107. The green coloured complex obeys Beer’s law in the concentration range 29.35 to 234.77 ppm for Ni(II) ion, while the optimum concentration range from Ringbom plot is found to be 58.69 to 234.77ppm. The photometric sensitivity and molar absorptivity at the 600nm are found to be 0.448µg/cm2 and 131 l mol-1cm-1 respectively. The standard free energy of formation of complex is -10.82 kcal/mole at 30oC. The complex is stable for one week. The reagent has also been found to give quite satisfactory results for Ni(II) present in alloy like brass, Nicrome and synthetic mixtures. The antimicrobial Activity of HIBAO and Ni-HIBAO complex have also been checked.
