摘要：
Ag/13X adsorbents were synthesized, characterized and tested for decontamination of gaseous effluents from I-131(2) at high temperatures. X-ray diffraction patterns showed that the Ag/13X samples maintained a stable structure after calcined at 650 A degrees C for 2 h. The decontamination factors achieved with 15 % Ag/13X and 20 % Ag/13X adsorbents for I-131(2) were nearly close to 10(3) at 650 A degrees C. In addition, 15 % Ag/13X had a stable performance for removal of I-131(2) at 550 and 650 A degrees C, even after calcined at 550 and 650 A degrees C for over 10 h, which might be suitable for future potential use during nuclear reactor operation or in the case of nuclear accidents.
