Selective Removal of Radionuclides from Radioactive Wastewater: Design and Synthesis of New Organic Small-Molecule Adsorbents

Project Details

Description

This proposal is divided into two parts: (1) development of new small-molecule adsorbents by using synthetic chemistry; (2) carrying out the adsorption experiments of radionuclides using the newly synthesized organic adsorbents. We will cooperate with 廣宏科技有限公司to develop a variety of organic small-molecule adsorbents, performing the extraction experiments of radionuclides in National Tsing-Hua University (NTHU). In contrast to traditional synthetic chemistry, we plan to employ the step-saving synthesis shortcuts to access various organic adsorbents bearing different functional groups containing nitrogen, phosphorus oxide, or sulfur moieties, aiming at the selective removal of different radionuclides from radioactive wastewater. The standards created by American Society for Testing and Materials (ASTM) will be applied to conduct the adsorption experiments, and we will focus on the investigation of selective extraction of the most abundant elements: cobalt and cesium. The ratio regarding the loading quantity of organic adsorbents versus radioactive wastewater will be optimized. We anticipate to obtain the effective and low-cost organic small-molecule adsorbents, eventually scaling up the molecules of interest to provide 廣宏科技efficient and sufficient adsorbents for the decontamination of radioactive wastewater produced by nuclear power plant.
