Abstract EN
The radiation chemical discoloration of aqueous solutions of cyanine dyes were studied using the radiolysis technique.
The spectral characteristics of radical were determined and the radiation – chemical yields of their formation and dye decomposition were measured.
The degradation of the two types of cyanine dyes with gamma source were studies.
Different parameters that effects on the radiolysis such as exposure doses and pH were studied.
The UV detector was used to analyze the degradation percentage.
The variation of the irradiation doses from 1 kGy to 10 kGy change the degradation from about 55% to 90% with a little difference in the stability of cyanine dyes that contain nitro group (P-NO2) than dimethyl group P-N(Me)2 due to the electron with drawing effect of nitro group.
The results obtained were used to study the applicability range and sensitivity of different type of cyanine dyes in aqueous solution to be used in chemical dosimetry purposes.
