Large amounts nanomaterials are fabricated as versatile products in the markets with the fast developing nanotechnology and manufacturing processes. Carboneous nanomaterials, such as fullerene nanoparticles, are widely used in various commercial products and have potential ecotoxicity and risks for human health. Three fullerenes nanoparticles prepared by sonication (SON/nC60, SON/nC70, SON/nPC60BM) were characterized by a Nanoparticle Tracking Analyzer (NTA), determined by a proposed Evaporation-redissolved approach and spiked into tap water, reservoir and sewage samples. These aqueous samples were then used liquid-liquid micro-extraction (LLME) to transfer into toluene and determined by a UV/Vis spectrophotometer. Asymmetric flow field flow-fractionation (AF4) were applied to separate the fullerene nanoparticles. The spiked fullerenes were also determined by a high performance liquid chromatography with a photodiode array detector (HPLC-PDA) and a HPLC-APPI-MS/MS. Furthermore, one commercial fullerenes-containing cosmetic was used to valid our analytical methods.
