TY - JOUR TI - Adsorption performance of silver-loaded activated carbon fibers AU - Yan Xue-Feng AU - Fan Xue-Rong AU - Wang Qiang AU - Shen Yue JN - Thermal Science PY - 2018 VL - 22 IS - 1 SP - 11 EP - 16 PT - Article AB - Silver-loaded activated carbon fiber is prepared, and its adsorption performance is studied experimentally using five methylene blue solutions with different concentrations under three different temperature conditions. The adsorption tests show that fibers adsorption increase as the increase of temperature, and there is an optimal value for solution concentration, beyond which its adsorption will de-crease. Fibers isothermal adsorption to methylene blue is different from those by the monolayer adsorption by Langmuir model and the multilayer adsorption by Freundlich model. Through the analysis of thermodynamic parameters, Gibbs free energy, standard entropy, and standard enthalpy, it is found that the fibers adsorption to methylene blue is an exothermic process of physical adsorption.
