摘要
探究物品的来源对于其固体废物属性鉴别尤其重要,土壤样品复杂多样,受到污染后污染特征不明显。利用正庚烷、乙醇-丙酮(73)溶剂分别对样品进行提取,将提取物做红外光谱分析,结果发现样品含有水的吸收峰及-CH3、-CH2-等碳氢键的吸收峰。利用气相色谱-质谱仪分析提取物,未检出明显的可溶解于正庚烷、乙醇-丙酮(73)溶剂的沸点低于200℃的易挥发物质,样品中不存在明显可检出的汽油、煤油、苯类、低碳的醇醚酮酯等化合物,该土壤样品被润滑油类物质污染。
It is particularly important to explore the source of materials for their solid waste identification.The soil samples are complex and diverse and the pollution characteristics of the polluted soil are not obvious.N-heptane and ethanol acetone(7:3)solvents were used to extract the identified samples in this study.The extracted materials were analyzed by infrared spectrometry and the results showed that the samples contain water absorption peaks and CH bond absorption peaks such as-CH3,-CH2-,etc.Then the extracted materials were analyzed by GC-MS.And no volatile matters with boiling point lower than 200℃which could dissolve in N-heptane,ethanol acetone(7:3).No gasoline,kerosene,benzene,low-carbon alcohol ether ketone ester and other compounds were found in the sample.The soil sample was polluted by lubricating oil.
