英文摘要	To prevent radioactive iodides from releasing into the environment in an accident of a nuclear power plant, silver-impregnated alumina (Ag/Al2O3) was fabricated, and its performance of radioactive iodine adsorption from high-temperature gas was tested. The silver loadings on alumina were obtained by ICP-OES and the texture properties of Ag/Al2O3 were characterized by N-2 adsorption-desorption. The Ag/Al2O3 was of reduced specific surface (107.2 m(2)/g at 650 degrees C). Crystalline phases of Ag/Al2O3 were confirmed through XRD characterization. After calcination at 650 degrees C for 2 h, the crystalline phase of Ag/Al2O3 changed. The I-131-removal efficiency of Ag/Al2O3 was tested at 100, 250, 350, 450 and 650 degrees C, with good decontamination factor values for the radioactive iodine. Silver-impregnated alumina can be applied as adsorbents to remove radioactive iodine at high temperatures in nuclear accident.; SCI(E); 中国科学引文数据库(CSCD); ARTICLE; twchu@pku.edu.cn; 4; 040303-01-040303-05; 26
