Characterization and optical properties of hen and begion eggs shell

Abstract

In this research, the physical properties of hen and begion

egg shell were investigated by using

different techniques; namely X

-

ray diffraction, X

-

ray (XRD) Fluorescence spectrometer (XRF) and

UV

-

visible spectroscopy devices.

XRF indicated the existence of (Calcium, Copper and Strontium) and their concentration

of

elements were different but the highest one of Calcium.

The optical properties were studied using UV

-

visible spectroscopy and the high absorption for

begion eggshell at 211 and 217nanometer we found energy band gap 3.7 and 4.08electron volt for

sample 0

.01 and 0.03gram respectively. Whereas the high absorption for hen eggshell at 244and

288nanometer we found energy band gap 3.91and 4.00electron volt for sample 0.01, and 0.03gram

respectively.

Also were study the stricture properties by X

-

ray diffraction and found to be hexagonal

for two samples.
