摘　　要：In this paper, six kinds of activated carbons such as Ag+-activated carbon, Cu2+- activated carbon, Fe3+- activated carbon, activated carbon, Ba2+- activated carbon and Ca2+- activated carbon were prepared. The model for estimating activated energy of desorption was established. Temperature-programmed desorption (TPD) experiments were conducted to measure the TPD curves of n-hexanol and then estimate the activation energy for desorption of n-hexanol on the activated carbons. Results showed that the activation energy for the desorption of n-hexanol on the Ag+- activated carbon, the Cu2+- activated carbon and the Fe3+- activated carbon were higher than those of n-hexanol on the activated carbon, the Ca2+- activated carbon and the Ba2+- activated carbon.In this paper, six kinds of activated carbons such as Ag+-activated carbon, Cu2+- activated carbon, Fe3+- activated carbon, activated carbon, Ba2+- activated carbon and Ca2+- activated carbon were prepared.
