| Abstract Sulfate (SO4)-2 is ubiquitous in groundwater, with both natural and anthropogenic sources. At high levels, sulfate can give water a bitter or astringent taste and can have mild laxative effects The aim of this work is to present experimental results on the evaluation and removal of Sulfate ions from drinking ground water in Wadi El-Assiuti – Egypt using anion exchange resin: Amberlyst A21. The drinking groundwater samples were collected from different places of El-Fath region (Assiut Government) Egypt Amberlyst A21 was characterized by swelling, solubility, thermal properties like: thermal gravimetric analysis (TGA) and differential thermal gravimetric (DTG), X-ray diffraction analysis, and scanning electron microscopy (SEM) were also determined and the data were discussed. Moreover, the present study, anion exchange resins was used to the removal of sulphate (SO4)-2 from ground water used as a drinking water. The effects of different parameters such as different resin dose, pH and contact time were examined. The results show that anion exchange resin (Amberlyst A21) has good affinity towards sulfate (SO4)-2 ion removal that uses especial conditions such as large weight of resin or long time for treatment. And the loading increases with acidity. The Langmuir constants model for (SO4)-2 ions are fitted well on the adsorption isotherms. The RL value in the present investigation was equal or less than one, indicating that the adsorption of (SO4)-2 ion by Amberlyst A21 is favorable. | ||||
