摘要：Using phenol, sodium dodecylbenzene sulfonate (DBS) and trimethyl benzyl ammonium chloride (TMBAC) as models, the adsorption behavior of water pollutant onto activated carbon at different temperatures was investigated. With all three substances and all activated carbon types, it was found that amount adsorbed decreased with increasing temperature, and that the effect of temperature was slight with large volumes of adsorbate and great with small volumes of adsorbate. With phenol and TMBAC, the amount adsorbed was greater with activated carbon with a small mean pore radius. It was concluded that, where adsorption from dilute aqueous solutions is involved, as in the advanced treatment of tap water, treatment efficacy would be improved by lower temperature, but that, in the treatment of wastewater with high pollutant concentrations and in the removal of substances easily adsorbed onto activated carbon, the effect of temperature could be disregarded.
