摘要
采用间歇平衡法研究多环芳烃在干酪根上的吸附机理,结果表明,干酪根对多环芳烃的吸附具有明显的非线性,推测干酪根对多环芳烃的吸附作用可能遵循的是双元吸附模式,总体吸附是由烷烃活动相中的分配过程和刚性大分子骨架内外表面的表面吸附共同作用的结果.
The sorption mechanism of polycyclic aromatic hydrocarbons （PAHs）on kerogen was studied by using a batch technique. The results showed that the sorption of PAHs on kerogen was significantly nonlinear and the nonlinear sorption behavior correlated well with the physiochemical properties of kerogen. We conjectured that sorption of PAHs on kerogen might follow a dual adsorption-partition process, the overall sorption might be the sum of the adsorption on external and internal surfaces of rigid backbones and partition into aliphatic mobile moieties.
