Synthesis of Amino Methylene Phosphonic Acid Resin-Supported Hydrated Cerium Oxide Hybrid Sorbent and its Application in Drinking Water

Abstract:

Article Preview

The hydrated cerium oxide (CeH) was synthesized and it was loaded on amino methylene phosphonic acid resin (APAR) to form the hybrid adsorbent CeH-APAR. The structure and thermal properties of CeH-APAR were tested by FTIR and TGA. And then, it was investigated that pH values and temperatures affected the adsorption property of CeH and CeH-APAR for fluoride ion. The results showed that CeH-APAR hybrid sorbent formed by Ce4+ and APAR with coordination bond is relatively stable below 270°C. Its adsorption property is similar to that of CeH, i.e. it is less affected by pH value, so it can be used in a wide pH range. Besides, under a stable pH, adsorption capacity of CeH-APAR also increases along with increasing temperature. As a result, it is a temperature-controlled sorbent and belongs to chemical adsorption.
