| Abstract | ||
| In this study attapulgite (AT) and filnt (FLN) clays are used as low cost adsorbents for adsorption of (R(6G)) in aqueous solution, and the factors affecting the adsorption process were studied, including the effect of pH which shows increase with increase of pH values to all clays in this study .The effect of equilibrium time was also studied and it was found that the best time was at (30 minutes) for (AT) , (40 minutes) for (FLN), then the effect of clay weight was studied , The results indicate that the percentage removal at equilibrium for (R(6G)) by using (AT) and (FLN) clay were 88% and 85% respectively. The adsorption isotherm was found to be similar to S-shape according to Gilles classification, and that obeys Freundlich isotherm model. | ||
