چکیده    Ion-exchange technology was used in the present work for removing sodium, sulphate, and chloride pollutants from the wastewater of the daura refinery. here, the batch experiments were conducted for examining the effects of mixing time and resin amount on the residual of pollutants and removal efficiency in this work. adsorption kinetics and thermodynamics were also studied. the adsorption was feasible, spontaneous, and endothermic, according to many thermodynamic parameters such as the enthalpy (δh), free energy (δg), and entropy (δs). chloride, sulfate, and sodium have removal efficiencies of (88, 91, and 82) % respectively. for sodium and sulfate, the best mixing time is 12 minutes, and for chloride, it is 14 minutes. the pseudo-second-order kinetic model fits sulfate adsorption on lewatit well, but the pseudo-first-order kinetic model fits sodium and chloride adsorption on lewatit well.
