Synthetic textile red dye removal from aqueous solution by adsorption onto pomegranate peel

الملخص EN

This study is conducted to evaluate the ability of using pomegranate peel as low cost material for adsorption one of synthetic textile dye (C.I.Direct Red 89 dye).

The removal of dye from aqueous solution is done by using pomegranate peel with two forms, as raw pomegranate peel (RPP) and activated carbon prepared from pomegranate peel(ACPP).

Some operational factors like contact time, pH, adsorbent dosage , and temperature were investigated in experimental work.

Also the thermodynamic parameters ΔH, ΔG, and ΔS were calculated, the result shows that the adsorption process of dye onto two forms of adsorbents was spontaneous and endothermic in nature.

Finally, the adsorption isotherm of experimental data we refitted for the Langmuir, and Freundlich equations
