| 摘 要： | 根据“相似易溶”原理，采用重量法和索氏抽提-紫外吸收光度法对含油污泥的油含量测定进行了研究，利用差重和含有芳香族化合物的石油及其产品在紫外区的吸收波长特性，采用了毒性较小的正己烷、石油醚或混合庚烷等作为萃取荆。根据试验结果可知，重量法具有药荆使用量少、标准偏差小（1.48％），结果准确等特点；紫外吸收光度法具有操作简便、数据重现性好等优点，适于芳烃含量较高的含油泥油含量的测定。 |

| Abstract: | Base on the principle of like dissolves like, the determination methods for oil concentration in oily sludge were studied with Gravimetric and Soxhlet extraction UV absorption spectrophotometry methods applied. Hexane for its least poisoning properties, petroleum Ether and mixed heptane were used as extraction solvent. Experimental data shows that the advantage of gravimetric method are less dosage of reagents used with high accuracy. UV absorption spectrophotometry are characterized by its simple operation procedures, high reappearance, and suitability is suitable for the oil sludge with high aromatic hydrocarbon content. |
| Keywords: | oily sludge oil concentration determination method |
