Abstract: Activated carbon is the main absorbent material in radon capturing. Studies on activated carbon radon capturing currently focus on ambient conditions, such as temperature, relative humidity, barometric pressure, radon concentration and the amount of absorbent. In order to analyze the influence of activated carbon molecular structure on radon absorption, oxidized activated carbon was prepared by oxidative activation of activated carbon. Experiments show differences in radon absorption between activated carbon and oxidized activated carbon. the relationship between adsorbents molecular structure and absorbability was analyzed.

Key words: carbon, adsorption, radon, modify
