Abstract

The study involves removing of [Alizarin Red S (ARS) and Alizarin yellow R (AYR)] by using Iraqi Siliceous Rocks Powder (SRP). Adsorption isotherms were studied and the factors which influence it, such as   temperature and salt effect. Adsorption isotherms of (ARS) were found to be comparable to Temkin equation. Adsorption isotherms of (AYR) were found to be comparable to Freundlich equation. The adsorption process on this surface was studied at different temperatures. The results showed that the adsorption of (ARS,AYR) on surface increased with increasing temperature (Endothermic process). According to the above results the thermodynamic functions (∆H, ∆G, ∆S) were calculated. The adsorption quantity increasing for (ARS, AYR) with increasing the saline solution .The Kinetics of the adsorption of (ARS,AYR) on surface was studied . The Kinetic experimental data properly correlated with (First and second-order kinetic) model.
