摘要：
The effect of iron doping on physical and chemical properties of activated carbon, the effect of initial concentration and temperature on adsorption behavior of adsorbents for aniline from water, and adsorption equilibrium and thermodynamics were investigated. The results show that Fe doping obviously increase acidic oxygen-containg groups of activated carbon surface. Effect of Fe doping on adsorption capacity of aniline at the low concentration is insignificant. Equilibrium adsorption uptake decreases with an increase in adsorption temperaure. Freundlich model can better describe adsorption behavior of aniline on AC and Fe/AC. Aniline adsorption is spontaneous and exothermic.
