Determination of Radioactive Cobalt
This article discusses a method for the determination of Cobalt‐60 (Co60) that uses a spectrophotometric measurement to determine the recovery of cobalt carrier, rather than the gravimetric method used in other procedures. Radiocobalt is concentrated from the water sample by precipitation as cobalt hydroxide. The precipitate is dissolved in nitric acid and then converted to the complex thiocyanate, which is extracted into methylisobutyl ketone. The cobalt is back extracted into water and precipitated as potassium cobaltinitrite, which is dissolved in nitric acid to form soluble cobalt nitrate. This solution is gamma counted with a well‐type scintillation counter. Recovery of cobalt carrier is determined by measuring the absorbance of the cobalt nitrate solution at 510 mμ.
