  • Spectrophotometric determination of cobalt in aqueous solution using di-2-pyridyl ketone derivatives
  • Published at:Not Found
  • A method for the spectrophotometric determination of cobalt(II) is presented, with a comparison of the binary complexes formed by cobalt(II) with di-2-pyridyl ketone nicotinoylhydrazone (DPKNH), di-2-pyridyl ketone 2-thiophenoylhydrazone (DPKTH) and di-2-pyridyl ketone benzoylhydrazone (DPKBH) in 50% (v/v) ethanolic solution. Cobalt(II) forms 1: 2 complexes with the three reagents. Maximum absorbance is at 372 nm for Co(II)- DPKNH, at 389 nm for Co(II)-DPKTH and at 370 nm for Co(II)-DPKBH
