Gamma radiation effects on UO2 (II)‎, Fe (II)‎ and Fe (III)‎ complexes with ferron and tiron in solutions

Abstract EN

UO2 (II) – ferron complex solution in ethanol and also Fe (II) – ferron or tiron complexes, and Fe (III) – ferron or tiron complexes in aqueous solutions were prepared and their composition was determined by the molar ratio method.

The complex solutions formed were found to obey Beer`s law within certain concentration ranges.

The color bleaching of these complex solutions upon gamma irradiation was followed spectrophotometrically.

The % color bleaching occurring in different complex solutions on using different gamma irradiation doses was calculated and plotted against the applied irradiation doses and the results obtained showed the existence of good linear relationships.

The linear sections were used as calibration curves for evaluating unknown gamma irradiation doses.

From the obtained results, it was concluded that UO2 (II) – ferron in ethanol, Fe (II) – ferron in water and Fe (III) – tiron in water could be used for dose evaluation within the dose ranges 0-600 kGy for UO2 (II) – ferron complex in ethanol, 0 – 25 kGy for Fe (II) – ferron complex in water and 0 – 10 kGy for Fe (III) – tiron in water
