Abstract

In this work a study was carried out to estimate the ability of Attapulgite clay as a new adsorbent for adsorption and removal of Methylene Blue dye from aqueous solutions. At first, the batch method was used to determine the best adsorption ratio from the concentration used of Methylene Blue dye between (50-10 mg/L), and the result show that the best concentration of dye was (10 mg/L) and the adsorption ratio was (86.28%). The shaking time that it equal to (35 min.) and the best pH value that give better adsorption ratio was (8). The effect of temperature and thermodynamic functions wear also studied and found that the adsorption ratio was increased with increased the temperature and the reaction was endothermic. After fixing the best conditions for the adsorption, the column method was used and the adsorption ratio was equal to (88.16%)
