Cetyltrimethylammonium Bromide-Coated Fe₃O₄ Magnetic ...
In this study, an effective solid phase extraction (SPE) method based on cetyltrimethylammonium bromide (CTAB)-coated Fe3O4 magnetic nanoparticles (MNPs) was developed for extraction of trace quantities of PAHs from natural waters. An enrichment factor of 800 was achieved within 5 min by use of 100 mg of Fe3O4 MNPs and 50 mg of CTAB.
