Development of Extraction Method of Polycyclic Aromatic Hydrocarbons from Sunflower Oil

Abstract

Polycyclic aromatic hydrocarbons (PAHs) adsorption extraction process from sunflower oil on activated carbon was studied. Specific adsorption values on activated charcoal-xenobiotic system for compounds of benzo(a)anthracene, benzo(a)pyrene, benzo(e)pyrene, chrysene, benzo(b)fluoranthene and their mixtures were investigated. Influence of phase contact time of system, ratio of components on degree of PAHs extraction under isothermal conditions (25 ± 0.01ºC) was studied. Degree of oil purification was controlled by method of high performance liquid chromatography with fluorescence detector (HPLC/FLD). Leaning on patterns found, optimal conditions for purification of raw sunflower oil from PAHs using activated charcoal and obtaining the matrix of sunflower oil proposed.
