Breakthrough curves for citric acid adsorption from aqueous solution onto ion-exchange resin at 20, 35, and 55?C have been\ninvestigated. To predict breakthrough curves, threemathematical models have been analyzed based on the values of the least square\nmethod parameters, Durbin-Watson test, and mean relative percent error and, finally, appropriate models have been achieved.\nModels are in good agreement with experimental data based on the results. To examine models reliabilities and accuracy, models\nhave been compared by various breakthrough curve data obtained by other investigators.The results show appropriate agreement\nand in some cases regression errors have been reduced to less than 1.0 percent
