文摘

One-step, combined microextraction technique for atmospheric aliphatic amines. Simultaneous derivatization and solvent-based extraction of amines in PM2.5. High recovery and enrichment with the aid of vortex agitation and RGO sorbent. High sensitivity and selectivity by derivatization of amines and GC–MS analysis. Successful application to PM2.5 filter sample analysis with good reproducibility.
