【Abstract】 In this paper,six kinds of activated carbons such as Ag + activated carbon,Cu 2+ activated carbon,Fe 3+ _activated carbon,activated carbon,Ba 2+ _activated carbon and Ca 2+ _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 on the activated carbons and then estimate the activation energy for desorption of n_hexanol on the activated carbons.The results showed that the activation energy for desorption of n_hexanol on the Ag +_activated carbon,the Cu 2+ _activated carbon and the Fe 3+ _activated carbon were higher than those of n_hexanol on the activated carbon,the Ca 2+ _activated carbon and the Ba 2+ _activated carbon.更多还原
