活性炭结构改性对氡吸附能力差异的分析研究

Study on radon absorption characterisitcs of structurally modified activated carbon

活性炭是吸附氡的主要吸附剂,但对于活性炭吸附氡的研究目前主要集中在外界环境条件、氡浓度的改变等对其吸附氡效率的影响。为了从活性炭自身结构分析其对氡吸附的影响程度,通过对普通活性炭进行氧化活化,比较二者的氡吸附能力,最后从二者自身结构的差异分析其与氡吸附能力的关系。

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.
