The problem of oil spill pollution associated with the transport of crude oil and its products across the globe is of serious concern. The sorption technique has proved to be promising for oil spill treatment but is limited by the hydrophilic nature of most natural organic sorbents. The combo of natural organic and inorganic sorbents have been found to enhance the hydrophobicity for oil sorption. Therefore this study was aimed at the preparation of a novel feldspar-banana peel biochar composite (FBPC) with enhanced hydrophobicity for the sorption of crude oil. The prepared sorbent was characterised by the scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques, while the crude oil was characterised using standard methods. Batch sorption was used to determine the effect of contact time (30–150 min), temperature (25–100 °C), pH (2.0–10.0), oil concentration (4.0–12.0 g/L) and sorbent dosage (0.1–0.5 g) on sorption. SEM analysis of FBPC revealed a porous structure, while XRD confirmed the crystalline phases of feldspar. The crude oil samples had pH (6.40–6.60), density (0.960 0 0.962 g/cm³), kinematic viscosity (24.0–27.6 cSt) and API gravity (24.25–24.51°). The Langmuir model with R² > 0.7781 presented the best fit than the Temkin and Freundlich model in the isotherm analysis, while the pseudo-second-order model with R² > 0.9711 was applicable in the kinetics of sorption. The thermodynamic analysis revealed a decrease in randomness at the crude oil-FBPC interface. The prepared FBPC was found to be an efficient inorganic–organic composite sorbent with enhanced hydrophobicity for the sorption of crude oil.

与原油及其产品在全球范围内的运输相关的漏油污染问题受到严重关注。吸附技术已被证明可用于溢油处理，但受到大多数天然有机吸附剂亲水性的限制。已发现天然有机和无机吸附剂的组合可增强油吸附的疏水性。因此，本研究旨在制备新型疏水性长石-香蕉皮生物炭复合材料（FBPC），以吸附原油。制备的吸附剂通过扫描电子显微镜（SEM）和X射线衍射（XRD）技术进行表征，而原油则使用标准方法进行表征。分批吸附法用于确定接触时间（30–150分钟），温度（25–100°C），pH（2）的影响。0–10.0），吸油率（4.0–12.0 g / L）和吸附剂剂量（0.1–0.5 g）。FBPC的SEM分析显示多孔结构，而X射线衍射证实了长石的结晶相。原油样品具有pH（6.40–6.60），密度（0.960 0 0.962 g / cm ³），运动粘度（24.0–27.6 cSt）和API重力（24.25–24.51°）。 在等温线分析中，R ² > 0.7781的Langmuir模型比Temkin和Freundlich模型表现出最佳拟合，而R ²  > 0.9711的拟二阶模型适用于吸附动力学。热力学分析表明，原油-FBPC界面处的随机性降低。发现制备的FBPC是一种有效的无机-有机复合吸附剂，具有增强的疏水性以吸附原油。
