Filtration d’une huile dopée avec quatre hydrocarbures aromatiques polycycliques (HAP) sur des plaques garnies en charbon actif

Improving the Quality of Baobab Oil by Filtration on Activated Carbon from the Fruit Capsules

“…These results are consistent with those obtained by Thiam (2018), Lacoste et al (2005) [27] and Sidani et al (2012) [26]. Indeed, Thiam (2018) had reported a decrease in acid and peroxide values from 4.72 mg KOH g −1 and 14.26 me-qO 2 •kg −1 respectively for crude oil to 2.56 mg KOH g −1 and 13.08 meqO 2 •kg −1 after treatment on 3% activated carbon.…”

“…The significant reduction in oxidation and rancidity products (free acids, hydroperoxides and toxic peroxides) in the oil can be explained by the fact that activated carbon adsorbs the various particles responsible for this phenomenon. Activated carbons have a porous structure made up of macropores, meso-pores and micropores, enabling them to adsorb certain particles [14] [26].…”

“…Lacoste et al (2005) reported that when activated carbon was added to bleaching earths, most of the polycyclic aromatic hydrocarbons (PAHs) were removed. Finally, Sidani et al (2012) had worked on the filtration of an oil doped with four polycyclic aromatic hydrocarbons. They used activated carbon-lined plates to lower PAH levels.…”
