ABSTRACT:
A sensitive and simple spectrophotometric method was developed for the determination of Chromium(VI) with Isonitriso p-isopropyl Acetophenone Phenyl Hydrazone. Chromium was complexed with Isonitriso p-isopropyl Acetophenone Phenyl Hydrazone and the reddish yellow colour complex was extracted into methyl isobutyl ketone. The absorbance of the complex was maximum at 443 nm. The molar absorptivity of the complex was 2.78 x 103lit.mol-1cm-1 and Sandell’s sensitivity was 2.67 x 10-2 µg/cm2. The system obeyed Beer’s law over the concentration range of 0.5 to 20 ppm. The composition of the complex (metal: ligand) was 1:6. This method was employed for the determination of chromium in Goa Beans and Soya Leaves Sample
