M. Fadly et M. Dawy, EFFECT OF GAMMA-RADIATION ON THE ELECTRONIC-SPECTRA OF POLY(METHYL METHACRYLATE) DOPED WITH SOME DIVALENT ND(10) CATION DITHIZONES, Polymer-plastics technology and engineering, 34(2), 1995, pp. 347-354
The electronic absorption spectra of dithizone (H(2)DZ) and its metal
complexes of Hg, Cd, and Zn doped in poly(methyl methacrylate), PMMA h
as been investigated before and after gamma-irradiation. It is found t
hat the complex formation resulted in significant changes in both the
position and the intensity of the electronic bands of H(2)DZ. gamma-Ra
diation causes remarkable decrease in the intensity of the most absorp
tion bands of the metal complexes. The rate of decrease depends on the
nature of the metal ions.
