ABSTRACT: In this study, an analytical method is developed to determine 15 polycyclic aromatic hydrocarbons (PAHs) in olive and refined pomace olive oils using HPLC coupled with a fluorescence detector. The standardised method of ultrasound-assisted solvent extraction consisted of liquid–liquid extraction with organic solvent and purification on C18 and Florisil bonded-phase cartridges was modi...
Thanks to advances in materials science and manufacturing technology, membranes are now available for stable liquid-liquid extraction processes. Rigorous calculation models can be used calculate the membrane areas required a specific separation task as well optimize module design. Rapid tests determine basic suitability kinetic parameters. Thus, general requirements exploiting advantages of thi...
Abstract Polycyclic aromatic hydrocarbons (PAHs) are classified as persistent and carcinogenic organic pollutants. PAHs contamination has been reported in water. Many of relevant regulatory bodies such as EU and EPA have regulated the limit levels for PAHs in drinking water. In this study, 13 priority polycyclic aromatic hydrocarbons (PAHs) were determined in tap water samples of Tehran and wat...
