Abstract:
In this work, Gum Arabic (Talha and Hashaba) Nano-material samples were
prepared with different Concentration (0.1, 0.3, 0.5, 0.7 and 0.9) m Molar by
doping with Iodine. Optical Properties of Gum Arabic doping by Different
Concentration of Iodine measured by using the UV- Spectroscopy min 1240,
The Nano crystal size of all samples was measured by XRD technique, and
study effect of different concentrations on the particle Size and crystal
properties of all samples. The study the effected of different concentration on
the optical parameters. For all samples the absorbance increases upon
increasing the concentration, while the transmission decreases. The value of
Energy band gap (Eg) decreased from (4.420) eV to (4.323) eV. The density
increasing by rated 0.5465 mg. Cm-3/molar. Particle Size decreasing by rated
2.41 nm / molar, and d-spacing were decrease molar rated 10-10m / molar. And
for FTIR there are found all this band (metal-oxygen vibration at difference
positions is due to the different values of metal ion-O , C-C stretch and CC-
H bending, O-H bending vibration , C=C stretching and stretching mode
of H-O-H bending vibration of free or absorbed water which implies that the
hydroxyl groups are retained in ferrites in all samples of Gum Arabic (Talha
and Hashaba
