The sorption of selected PAHs onto sediment components and graphene wool were studied. Different natural organic matter (NOM)- mineral-deficient (MDF), mineral-rich (MRF), and black carbon (BCF) fractions were recovered from natural sediment (NAS) using sequential separation methods. Detailed characterization of sediment components using BET, ICP-OES, SEM-EDS, XRD, and FTIR were carried out and significant changes in the physicochemical properties of sorbents due to the treatment procedure were revealed. Experimental data showed that a pseudo-second-order and Freundlich adsorption model best fit kinetic and isotherm studies, validated by the least values of Error Sum of Squares (SSE). Isotherm data revealed that complementary processes involving both multilayer adsorption and partitioning of PAHs occurred. NAS, BCF, and MDF with higher % OC had higher Freundlich and maximum adsorption capacities (${\mathit{K}}_f$ and ${\mathit{q}}_{max}$) than MRF for PAHs and an S-type sorption curve (N > 1) dominated the PAH-NOM interaction, with few exceptions for LMW PAHs. MRF significantly diminished the efficiency of graphene wool in the removal of selected PAHs from aqueous solution, as both adsorption capacity (${\mathit{K}}_d$) and efficiency reduced from 16.9 g L⁻¹ and 95.4% to 0.3 g L⁻¹ and 18.5% respectively. Sorption of the selected PAHs was slightly favored under acidic pH and higher temperatures. The sorption reaction was endothermic for NAPH & PHEN, and exothermic for PYR & PERY. Furthermore, aromaticity and hydrophobic moieties of the different PAHs and NOM significantly influenced the $\pi$-$\pi$ and hydrophobic-organophilic interactions that may have occurred, which led to some degree of irreversible sorption as shown by H-indices. Therefore, the probable impact of each NOM fraction on the mobility and environmental risk management/remediation of PAHs is herewith evaluated.

研究了所选PAHs在沉积物组分和石墨烯羊毛上的吸附。使用顺序分离方法从天然沉积物（NAS）中回收了不同的天然有机物（NOM）-矿物质缺乏（MDF），富矿物质（MRF）和黑碳（BCF）馏分。使用BET，ICP-OES，SEM-EDS，XRD和FTIR对沉积物成分进行了详细表征，并揭示了由于处理程序而导致的吸附剂理化性质的重大变化。实验数据表明，伪二阶和Freundlich吸附模型最适合动力学和等温线研究，并通过最小平方误差和（SSE）的值进行了验证。等温线数据显示发生了涉及多层吸附和PAHs分配的互补过程。NAS，BCF，${\mathit{ķ}}_F$ 和 ${\mathit{q}}_{米\mathrm{一种}X}$PAHs的MRF除外，S型吸附曲线（N > 1）主导了PAH-NOM相互作用，而LMW PAHs例外。MRF显着降低了石墨烯羊毛从水溶液中去除所选PAH的效率，因为两者的吸附能力（${\mathit{ķ}}_d$）和效率分别从16.9 g L ^-1和95.4％降至0.3 g L ^-1和18.5％。在酸性pH和较高温度下，对选择的PAHs的吸附稍受支持。NAPH和PHEN的吸附反应是吸热的，PYR和PERY的吸附反应是放热的。此外，不同PAHs和NOM的芳香性和疏水部分显着影响了$\pi$--$\pi$可能发生的疏水和亲有机相互作用，导致一定程度的不可逆吸附，如H指数所示。因此，据此评估了每个NOM组分对PAHs的迁移率和环境风险管理/修复的可能影响。
