Sandy soil samples spiked with Bonny light crude oil were subsequently treated with Fenton's reagent at acidic, neutral, and basic pH ranges. Oil extracts from these samples including an untreated one were analyzed 1 week later with a gas chromatograph to provide evidence of hydrocarbon depletion by the oxidant. The reduction of three broad hydrocarbon groups-total petroleum hydrocarbon (TPH); benzene, toluene, ethylbenzene, and xylene (BTEX); and polycyclic aromatic hydrocarbon (PAH) were investigated at various pHs. Hydrocarbon removal was efficient, with treatment at the acidic pH giving the highest removal of about 96% for PAH, 99% for BTEX, and some TPH components experiencing complete disappearance. The four-ringed PAHs were depleted more than their three-ringed counterparts at the studied pH ranges.
沙土地样中加入邦尼轻质原油后，用芬顿试剂在酸性、中性和碱性 pH 值范围内进行处理。这些样品的油提取物（包括未处理的样品）在一周后用气相色谱仪进行分析，以提供氧化剂消耗烃类的证据。在不同的 pH 值条件下，研究了三种宽范围的烃类——总石油烃（TPH）、苯、甲苯、乙苯和二甲苯（BTEX）和多环芳烃（PAH）的减少情况。在酸性 pH 值下，处理效果最高，约 96%的 PAH、99%的 BTEX 和一些 TPH 成分完全消失，表明烃类去除效率很高。在所研究的 pH 值范围内，四环 PAH 的消耗比三环 PAH 多。
