STUDY OF ADSORPTION METHYLENE BLUE DYE FROM AQUEOUS SOLUTIONS BY ATTAPULGITE CLAY BY THE BATCH AND THE COLUMN METHOD

Abstract

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