摘要: In chromatographic analysis of polycyclic aromatic hydrocarbons (PAH), three important aspects must be taken into account: losses by sorption onto the containers, association with dissolved organic material, and need for high preconcentration factors. this work, fluorescence detection was used liquid after cloud point nonionic surfactant Triton X-114. Negligible PAH containers recoveries, even in presence considerable levels humic acids, are additional advantages proposed micelle-mediated methodology
