SPECTROPHOTOMETRIC STUDY OF THE COMPLEXATION REACTION BETWEEN COBALT (II) AND 2-HYDROXY-4N-BUTOXY-5-BROMO ACETOPHENONE OXIME

Abstract

Author(s): RG.Parmar and SS.Shah

2-Hydroxy-4n-butoxy acetophenone (HBA) was earlier employed as an analytical reagent for the gravimetric, amperometric and spectrophotometric determination of various metal ions. Further study on its bromo substituted oxime shows that it forms a stable to give yellowish brown complex with Cobalt(II) and a detailed spectrophotometric study is carried out. This complex obeys Beer’s law 14.73 ?g/ml to 117.86 ?g/ml of Co(II) in chloroform at 640 nm. The stability constant of the chelate is 4.45X108. The molar absorptivity and Sendell’s sensitivity are found to be 312 lmol-1 cm-1 and 0.19 μg cm-2, respectively at 640 nm. The solid compex is isolated and its UV and IR spectra are studied.
