Abstract

Activated carbon (AC) is widely used for adsorbent and supporter of catalyst owing to its efficient adsorption capacity and large specific surface area. The objective of this study is to investigate chlorine adsorption properties of Cu/AC, Ag/AC and Pd/AC, which were prepared by impregnation method. The samples were characterized by X-ray diffraction and Fourier transform infrared spectroscopy techniques. The experimental data showed the loading of copper, silver and palladium could significantly improve the adsorption capacity of activated carbon for chlorine. The maximal adsorption of Cu/AC with 5 wt. % copper content could reach 32.73 % at 30 °C under 0.22 MPa. While the adsorption capacity of 9 wt. % Ag/AC and 9 wt. % Pd/AC are larger, of which the values were 33.46 and 34 %, respectively. Moreover, the structural framework of Cu/AC, Ag/AC and Pd/AC still existed and its adsorption ability remained stable after absorbing continuously for several times.
