Abstract EN

In the prersent study the peel chicken eggs with activated internal membranes by concentrated sulfuric acid and sodium bicarbonate as materials natural adsorbent vital to removed organic pigments such as methyl orange dye, was used to addressed the following :- 1- study the chemical composition (moisture, ash, protein and fat): Their percentag in the peels with internal membranes reached to (1.398, 4.383, 4.900 and 0.989) % respectively, as well as metal ions in ash was estimated, Whever the percentag of calcium, potassium, magnesium , iron, copper, zinc and manganese in the peels with internal membranes were 28.70, 6.90, 8.64, 1.860, Nil, 0.0430 and 0.5860 % respectively.

2- conduct of quality analysis for the components of eggshells which included.

Study of infrared (FTIR) for components, where we observed absorption packages that beloing to many active groups such as (OH-) , (NH) , (C-H) , (C-H, C = O) , (CH2, CH3) and (C-C, C-O).

Examination by diffraction X-ray technique, results indicated that there are a number of peaks vary in their severity and location, but being in similar as a sharp peaks and this indicated the possession of eggshells installation of crystalline accurate.

Conducting a study using electronic scanning, results showed that the eggshells components have a porous surface as well as crystalline shape that make it as effective component and well suited material to linked with saveral material that need to be removed.

3- Also the ability of eggshells peels with activated internal membranes) to linked with water and oils were studied (using sunflower, olives and corn) oils , and the results indicated thier ability to linked with water and oils,with a difference in the ratios of linked with oils depending on the type of oil.

Ability of peel with activated internal membranes to removed methyl orange dye was studied, the results showed that the optimal conditions for the process of adsorption were to be the time of the contact (20) min, temperature (30) C, primary and concentration (25) ppm in size (50) ml and the weight of adsorbent material (0.5) g, The percentage of removal were decreased with increasing pH where the highest percentage for the removal was reached to 50.30 % when (pH = 2) and the lowest percentage of removing was 37.50 % when (pH = 8).

4- Study of the isotherms adsorption.The study showed that the adsorption to methyl orange dye by eggshells with activated internal membranes was submited to Gliese,s classification bacause the isotherms take shape (S) as well as submited to the equation lakmiar at (pH = 7) within the range of concentrations of the dye (10-30) ppm and the degree of temperature (30) C and time of (30) min and the weight (1) g.
