摘　　要：通过对快速溶剂萃取油气化探土壤样品中芳烃的空白实验、样品量,萃取的温度、压力、时间等检测条件的优化,确定了最佳萃取条件。运用重复性实验对方法进行评价,与常规萃取效果进行比较,选择南阳凹陷南部北马庄地区的一条已知地质剖面,开展快速溶剂萃取—荧光法的应用效果验证,研究结果表明该指标对圈划区域异常有帮助。Through optimizing the detecting conditions of the aromatic hydrocarbon for soil samples,such as the blank experiment,sample weight,extraction temperature and extraction pressure,the authors obtained the best analysis conditions.According to the experimental results,the method has been established.Methodological indicators such as repeatability has been used to evaluate the method.Compared with the conventional extraction effect,the extraction rate of rapid solvent extraction has been increased.1n a known geological section south of Nanyang sag,North Ma Zhuang area,the application effect of rapid solvent extraction with fluorescence method was carried out.The results show that this method can describe the regional geochemical anomalies.
