  • Title: Extractive spectrophotometric determination of cobalt using Cyanex-272.
    Author: Reddy BR, Sarma PV.
    Journal: Talanta; 1994 Aug; 41(8):1335-9. PubMed ID: 18966075.
    Abstract:
    Cyanex-272 forms a blue-colored complex with Co(II) in the organic phase. The complex shows three absorption maxima. The peak at 635 nm has been used for developing a spectrophotometric procedure for cobalt determination. Beer's law was found to be obeyed in the range 0.295-2.36 mg of cobalt. The nature of the extracted species was found to be CoR(2).HR. The molar absorptivity was found to be 3.07 x 10(2) l. mol(-1). cm(-1) at 635 nm. The method was applied for cobalt determination in solutions obtained from Beta Cake and a super alloy and was found to give values close to the actual ones. Easy regeneration of the reagent (Cyanex-272) for re-use is the main advantage of the present method.
