Determination of cobalt in the oxysynthesis products using the atomic absorption method

  • 10 Accesses

Conclusions

  1. 1.

    An atomic-absorption method has been developed for determining cobalt in oxysynthesis products in organic solutions, without preliminary chemical treatment.

  2. 2.

    A study has been made of the effect of the composition of the organic base of the samples analyzed, and of iron and nickel on the results of the determination of cobalt.

  3. 3.

    The sensitivity achieved in determining cobalt in organic solutions is 1·10−4%.

  4. 4.

    The relative error of the analysis is 6–10%.
