Abstract

The removal of nutrients in wastewater is a critical issue in water treatment because released nutrients can cause serious adverse effects in water systems or the aquatic environment. In this study, a high-performing polymeric anion-exchange resin was developed for the removal of nutrients from wastewater. The resins were prepared by chloromethylation followed by amination under preferred conditions. The resins were investigated for the removal of nutrients such as phosphate, nitrate, and fluoride from water. The density of functional groups on the synthesized resin was approximately 33 % higher than on commercialized resins, and the specific surface area of synthesized resin was increased by approximately tenfold compared with commercialized resins. The adsorption capacity of synthesized resins (AMP16-FeCl3) for anions was 285.8 mg/g, which was approximately three times higher than the capacity of commercialized resin (AMP16-OH). A study of the effects of the types of counterions and functional groups found that resins having hydroxide ion as a counterion showed higher capacity and selectivity for phosphate ion and that dimethylethanolamine as a resin functional group of resin was more efficient than trimethylamine.
