焦炉煤气苯并(a)芘含量提取处理方法的探讨

Discussion on Extraction Methods of B(a)P Content from Coke Oven Gas

阐述了对焦炉煤气中苯并(a)芘含量提取处理方法中的索氏法和超声法的两种方法,分析了两种方法测定相同含浓度苯并(a)芘含量样品测试数据差异及产生原因,用实验数据分析说明了使用超声法作为测定焦炉煤气中苯并(a)芘含量是一种最佳的处理方法。

Suo＇s method and ultrasonic method for extracting B（a）P （Benzo（a）Pyrene） content from coke oven gas were introduced. The two methods were used to test the samples containing same density of B （a）P. Differences of the testing data and causes produced were analyzed. The testing results showed that the ultrasonic method was the best method to test B （a）P content in coke oven gas.
