摘要
研究了测定土壤中石油类含量的方法,采用直接用CCl4从土壤中萃取石油类的方法,再借用HJ637—2012《水质石油类和动植物油类的测定红外分光光度法》测定萃取液CCl4中石油类的含量。该分析方法在土壤分析样品为10g时,确定了最佳的萃取剂体积50mL、萃取时间6h、萃取温度55℃等影响测量结果的因素。该方法不仅操作简单、经济、省时、省力,而且测定结果也较为接近真实数值,填补了企业环境保护管理工作中判定土壤污染严重程度时缺少监测分析方法的空白。
The method for the determination of oil content in soilwas studied.The oil was directly extracted from soil by CCl4 and was determined by the standard''Water Quality-Determination of Petroleum Oils and Animal and Vegetable Oils-Infrared Spectrophotometry'(HJ 637—2012).When the soil sample was 10 g,the optimum extraction volume was 50 mL,extraction time was 6hand extraction temperature was 55℃.The method is not only simple,economical,time-saving and labor-saving,but also the determination results is more close to the true value,filling the blank in the enterprise management of environmental protection work about assessing soil pollution severity.
