Research on Characterization and Application of High-Performance Ion Exchange Material

Abstract:

The object of this research is to investigate the removal of nitrogen in the form of ammonium ion (NH4+-N) from aqueous solutions using Na-form of high-performance ammonium ion-exchange material. The Chinese Kaolin from the province of Guangzhou is used as the raw material and modified to prepare the ion-exchange materials. According to CEC measurement, the obtained ammonium ion-exchange material had an ammonium ion exchange capacity greater than 75mgNH4+-N/g and can be used to remove ammonia nitrogen in water treatment. In this paper, several surface feature evaluation methods（SEM、XPS、IR）are used to discuss and analyze the modification process of kaolin and the action mechanism and modification results of the ammonia ion exchange material.
