摘要：

The modified activated carbon adsorbents were prepared by impregnation method for removal of arsine (AsH3). The results show that the activated carbons modified with sulfonated cobalt phthalocyanine (CoPcS) and Cu(NO3)(2) (denoted as Co/Cu) is found to have significantly enhanced adsorption removal ability. The effects of CoPcS content, calcination temperature, O-2 content and pore structure on the AsH3 adsorption are investigated. The optimum conditions for removal of AsH3 are 0.02 wt% of CoPcS content, 400 A degrees C of calcination temperature and 4 vol% of O-2 content, respectively. The regions of micropores (14.7 < pore width < 20 ) and mesopores (20 < pore width < 43.4 ) play the predominant role for adsorbing AsH3. The regeneration efficiency of deactivated Co/Cu/AC adsorbent is up to 71.2 %.
