Abstract

Abstract: The removal of bromate from aqueous medium by Amberlite IRA-400 anion exchange resin was explored in order to identify the capability of this resin to remove bromate from real water samples. The effects of several physicochemical parameters such as contact time, initial concentration, initial pH, and temperature were studied. The concentration of was determined using ultra-performance liquid chromatography–tandem mass spectrometry. The adsorption kinetics and isotherms were well fitted by pseudo-second-order model and Freundlich model, respectively. The adsorption was evaluated thermodynamically and the results showed the endothermic nature of adsorption as the value of ∆ H o was positive. The negative values of ∆ G o revealed the spontaneity of process. The analytical application of Amberlite IRA-400 for real water sample analysis was studied with very promising results.
