中文摘要：

通过静态吸附实验，研究了北京地区土壤对菲的吸附行为，考察了温度和表面活性剂对菲吸附的影响。结果表明，6种土样对菲的吸附等温线均较好地符合Freundlich吸附模式，其吸附能力的大小顺序为：轻壤土〉轻粘土〉砂壤土〉中壤土〉重壤土〉紧砂土；温度升高不利于菲在土壤中的吸附；十二烷基苯磺酸钠（LAS）和十六烷基三甲基溴化铵（CTAB）均利于菲在土壤表面的解吸，LAS和CTAB对菲的解吸率最高可达66．2％和31．8％，且LAS的解吸效果更好。

英文摘要：

Equilibrium experiments of soil adsorption of phenanthrene were performed to determine the effects of temperature and surfactants on the adsorptive capacities. The adsorptive capacities vs. equilibrium concentration data of phenanthrene for six Beijin soil samples were well represented by the Freundlich isotherm model; the declining order of the phenanthrene capacity was： light loam, light clay, sandy loam, medium loam, dense loam and dense sand. The adsorptive capacity declined at a higher temperature. Surfactants hexadecyl trimethyl ammonium bromide （CTAB） was a more effective surfactant than sodium dodecyl benzene sulfonate （LAS） for enhanced desorption of phenanthrene from soil achieving a higher degree of desorption relative to CTAB （66.2 % vs. 31.8 %）.
