phytoremediation of soil contaminated with petroleum was assessed in this study. A method of soil sample preparation for determining the total content of petroleum products by infrared spectrophotometry has been developed. It is a one-stage extraction method with minimal use of carbon tetrachloride as an extractant. This soil sample preparation method was environmentally friendly and cost-effective, as it required a significantly lower amount of extractant (15-30 ml of tetrachloromethane) compared to the commonly used threefold extraction method, which uses up to 150 ml of extractant. The extraction degree of petroleum products (PP) was determined to be from 81.78 % to 94.22 % after two days of extraction using the additive method of determining PP. It was observed that the presence of different fertilizer additives in the soil samples led to a reduction in the determined PP content in the following series: "without fertilizer" - "Biochar" additive - "Biohumus" additive. These results were compared with reference samples that did not involve the use of . Furthermore, the main thermolysis stages of petroleum products sorbed by the soil matrix and the thermal behavior of an artificial soil sample spiked with PP were examined. Detailed interpretation of thermograms of laboratory soil samples was conducted at various phytoremediation stages.
本研究评估了对受石油污染土壤的植物修复效果。开发了一种通过红外分光光度法测定石油产品总含量的土壤样品制备方法。这是一种单阶段萃取方法，使用四氯化碳作为萃取剂的量最少。这种土壤样品制备方法对环境友好且具有成本效益，因为与常用的三重萃取方法相比，它所需的萃取剂显著更少（15 - 30毫升四氯甲烷），常用方法使用多达150毫升萃取剂。采用测定石油产品的添加剂法萃取两天后，石油产品的萃取率为81.78%至94.22%。观察到土壤样品中不同肥料添加剂的存在导致所测定的石油产品含量按以下顺序降低：“无肥料” - “生物炭”添加剂 - “生物腐殖质”添加剂。将这些结果与未使用……的参考样品进行了比较。此外，还研究了被土壤基质吸附的石油产品的主要热解阶段以及添加了石油产品的人工土壤样品的热行为。在不同植物修复阶段对实验室土壤样品的热重曲线进行了详细解读。
