Abstract EN

The El-gash river sand was analyzed for grain size, The specific surface area , The point of zero charge (pHpzc), X-ray diffraction (XRD) and scanned by Electron Microscopy (SEM).

The grain-size analysis of the analyzed sample revealed that it contains the fraction of (< 0.063 - >2.00 mm).

The grains of the analyzed sample are Fine to medium-grained, sub rounded to sub angular grains and moderately sorted.

It has been found that the point of zero charge (7.89) and the specific surface area( 10.35 m2/g).

The X-ray diffraction analysis showed that the Studied sample composes of the following minerals: quartz, albite, muscovite and anorthoclase.

The Energy Dispersive X-ray Spectrum Scope(EDX) analysis shows that the Studied contains dominantly silica and aluminum.

However, the elements: iron, magnesium, sodium, calcium, potassium and manganese are occur in lesser amounts.

The adsorption equilibrium isotherms of methylene blue onto El- gash river sand were studied and modeled.

In order to determine the best fit isotherm, the experimental equilibrium data were analyzed using thirteen adsorption isotherm models with two- parameter equations- Langmuir and Freundlich isotherms; nine three-parameter equations - Sips, Langmuir-Freundlich and Toth isotherms.

The results reveal that the adsorption isotherm models fitted the experimental data in the order: Langmuir(two-parameter) > Langmuir-Frcundlich = Sips(three-paramcter) > Toth(threc- parameter) > Freundlich(two-parameter.
