| 摘 要： | 应用振荡平衡实验方法对萘在地质吸附剂上的吸附和解吸行为进行了研究,结果表明:萘在地质吸附剂上的吸附与解吸均呈现出明显的非线性和解吸滞后现象,这种吸附与解吸特性可能与地质吸附剂的内部结构之间存在一定的内在联系,结构的刚性、还原性和芳香性越大的地质吸附剂,对萘吸附和解吸的非线性愈强,解吸滞后愈明显.

| Abstract: | The sorption and desorption behavior of naphthalene on geosorbents were studied through the surged equilibrium experiment methods. The results showed that the sorption and desorption of naphthalene on geosorbents exhibited obviously nonlinear and sorption-desorption hysteretic, the sorption and desorption characteristics might correlate with the structure of geosorbents. The sorption and desorption of naphthalene on the more rigidity, more reductive and more aromatic geosorbents exhibited more nonlinear and more sorption-desorption hysteretie. |
