Mustafa, R.AbdElgani, Aldesogi Omer Hamed,Abdalsakhi. S. Mohammed, Mathany Bashir Osman Abstract: In this work, Gum Arabic (Talha) Nano-material samples were prepared withdifferent Concentration(0.1 ,0.3 ,0.5 ,0.7 and 0.9) m Molar by doping with Iodine.The Nano crystal size of allsamples was fond byXRD technique, and study effect of different concentrations on theparticle Sizeand crystal properties of all samples.The densityincreasing by rat 0.5465 mg. cm-3/molar. particle Sizedecreasing by rated 2.41 nm / molar,and d-spacing were decrease molar rated 10-10m / molar.
