摘要
本文用溶剂萃取法和热重法测量了柴油机排气微粒中可溶有机成份(SOF),研究了SOF随发动机负荷的变化关系,并比较了溶剂萃取法与热重法所得结果。还对微粒中的苯并(a)芘进行了定量分析。
Two techniques, solvent ertractjon and thermogravimetry(TG), were used to measure the soluble organic fraction (SOF) in diesel exhaust particulates. The change of SOF with engine load was showed, and the results of solvent extraction were compared with that of TG, The benzo( a)pyrene existed in diesel particulation was also analyzed quantitatively and reported.
