The demineralized fraction (DM), lipid-free fraction (LF), nonhydrolyzable organic carbon fraction (NHC), and black carbon (BC) were isolated from five marine surface sediments, and they were characterized by elemental analysis as well as CO₂ and N₂ adsorption techniques, respectively. The NHC fractions were characterized using advanced solid-state ¹³C nuclear magnetic resonance (NMR) and x-ray photoelectron spectroscopy (XPS). Then, the sorption isotherms of phenanthrene (Phen) and nonylphenol (NP) on all of the samples were investigated by a batch technique. The CO₂ micropore volumes were corrected for the outer specific surface areas (SSAs) by using the N₂-SSA. Significant correlations between the micropore-filling volumes of Phen and NP and the micropore volumes suggested that the micropore-filling mechanism dominated the Phen and NP sorption. Meanwhile, the (O + N)/C atomic ratios were negatively and significantly correlated with the sorption capacities of Phen and NP, indicating that the sedimentary organic matter (SOM) polarity also played a significant role in the sorption process. In addition, a strong linear correlation was demonstrated between the aromatic C and the sorption capacity of Phen for the NHC fractions. This study demonstrates the importance of the micropores, polarity, and aromaticity on the sorption processes of Phen and NP in the sediments.

从五个海洋表层沉积物中分离出脱矿物质部分（DM），无脂质部分（LF），不可水解有机碳部分（NHC）和黑碳（BC），并通过元素分析，CO ₂和CO _2对其进行了表征。N ₂吸附技术分别。使用先进的固态¹³ C核磁共振（NMR）和X射线光电子能谱（XPS）对NHC馏分进行表征。然后，采用分批技术研究了菲（Phen）和壬基酚（NP）在所有样品上的吸附等温线。通过使用N ₂校正了外部比表面积（SSA）的CO ₂微孔体积-SSA。Phen和NP的微孔填充量与微孔体积之间的显着相关性表明，微孔填充机制主导了Phen和NP的吸附。同时，（O + N）/ C原子比与Phen和NP的吸附能力呈负相关且显着相关，表明沉积有机质（SOM）极性在吸附过程中也起着重要作用。此外，芳香族碳与Phen对NHC馏分的吸附能力之间显示出很强的线性相关性。这项研究证明了微孔，极性和芳香性对沉积物中Phen和NP吸附过程的重要性。
