OP17- Development of DLLME-SFOD/GC-MS Method for UV Filter Determination Cemile Yücel1*, Serenay Ceren Tüzün1 , Hasan Ertaş2 , İlgi Karapınar1 , F. Nil Ertaş2* 1Dokuz Eylül University, Department of Environmental Engineering, Tınaztepe Campus, Izmir, Turkey 2Ege University, Science Faculty, Department of Chemistry, Bornova, Izmir, Turkey *Corresponding Author: , The term of UV filters refers to a group of chemicals those absorb the ultraviolet light and since they are widely used in plastic, paint, and rubber industry as well as the cosmetic sector, their levels in surface waters are increasing in last decades1 . These compounds tend to accumulate in water, sewage sludge and biota and behave like an endocrine disruptor, altering the normal functioning of organisms2 . Due to their harmful effects, UV filters have been included in the European Union monitoring list (2015/495/EU) and therefore, their accurate and sensitive analysis in environmental samples is of great importance. Present study described a method development for selected group of UV filters including 2,4- dihydroxybenzophenone or benzophenone-1 (BP-1), Benzophenone-3 (BP-3), 3- Benzylidene camphor (3BC), 2-ethyl hexyl-4-(dimethyl amino) benzoate (EDP), 2-ethyl-hexyl-4- trimethoxycinnamate(EHMC), Ethylhexyl salicylate (EHS), Homosalate (HMS), Isoamyl pmethoxycinnamate (IAMC), 4-Methylbenzylidene camphor (4-MBC) and Octocrylene (OC) in surface waters. The standard mixture was subjected to solidification of floating organic droplet (DLLME-SFOD) followed by injector port silylation coupled with gas chromatography – tandem mass spectrometry for determining organic UV filters in ultra pure water. A series of parameters, including injection port temperature, purge off time, pH of water, extraction solvent type and dispersive solvent type enhancing the response of the UV filters were systematically investigated by using different statistical experimental design methods to determine the significant factors.
