柴油机多环芳香烃类污染物的测量方法
Measurement method of polycyclic aromatic hydrocarbon emission of diesel engine
摘要
Abstract
The polycyclic aromatic hydrocarbons (PAHs) of diesel engine exhaust were measured by a method of using Teflon filter and XAD-2 collection, as well as ultrasonic extraction, Soxhlet extraction and GC-MS analysis.The results showed that concentration of different component in PAHs and the peak area had a good linear relationship in the experimental concentration range, and the linear correlation coefficient was above 0.99.Linear range was wider with 0.0125-80μg/mL.The method was more efficient for samples collection, and extraction efficiency was above 95％.The method had more repeatability, and relative standard deviation was less than 15％.Recoveries of filter samples were 70.1％-95.9％, the recoveries of adsorbent samples were 77.0％-102.6％.The method had higher sensitivity with minimum detection limit of 0.04 μg/m3, so it can be used for rapid analysis of PAHs content on diesel engine.关键词
