摘要
Abstract
The study is about the identification of activated carbon, which was made by vapor activation,from coconut shell, almond shell and coal was preliminarily studied by stable isotope ratio technique. Statistical Package for the Social Sciences (SPSS) statistics of 65 kinds of activated carbon found that the δ13Cvalues of coal-based activated carbon, the almond shell activated carbon and the coconut shell activated carbon were-24.3‰--22.1‰,-25.9‰--24.4‰and-25.7‰--24.6‰, respectively. Further studies analyse of the relationship between δ13Cand δ18O,δ13Cand δ2H, the δ13Cvalue asvertical axis showed that the δ13Cvalues of different kinds of activated carbon were located in different interval. The δ13Cvalues of coal-based activated carbon were above Y=-24.325, which could distinguish clearly from almond shell and coconut shell activated carbon.Between Y=-25.031 and Y=-24.325. The most part of δ13Cvalues of the almond shell activated carbon were Y=-25.031--24.325 and those of the coconut shell activated carbon were below Y=-25.031. Although the interval of coconut shell and almond shell activated carbon were different, but part of those were overlap. According to this model, the correct classification of activated carbon from coal,almond shell and coconut shell were 100%,40% and 90.32%.关键词
