摘要
This paper set up the identification method of BF3/ methanol derivatization,GC-MS for analyzing organic acid in PM2.5 aerosol. The result shows that this method is reliable for monitoring the polar organic acid. Total 34 polar organic acids were identified and quantified, including 23 n-fatty acids and 6 dicarboxylic acids, 5 aromatic acids.The total concentration of n-fatty acids was 62-664 ng·m-3, and the C16 acid was the most abundant acid,followed by C18.
