摘要

Abstract

In this study

we reported on the concept and practical use of cation exchange resin (CER) for removing anions in water via pretreating the CER with metal salts. The cation exchange resin-supported iron and magnesium oxides/hydroxides composite (Fe-Mg/CER) was synthesized and introduced as a new and potential adsorbent for selective removal of nitrate ion in the water environment. Characteristics of Fe-Mg/CER were determined by techniques such as Fourier-transform infrared spectroscopy

scanning electron microscopy

and X-ray diffraction. The results showed that Fe-Mg/CER material had a high nitrate adsorption capacity of 200 mg NO

·g

-1

with a fast equilibrium adsorption time of 30 min at pH 5. In addition

it had good durability of at least 10 times of regeneration

which could be applied to practical water and wastewater treatment.
