DETERMINATION OF SUNSCREEN COMPOUNDS IN WATER SAMPLES BY SILICONE ROD EXTRACTION

Silicone rod extraction (SR) is a siloxane-based methodology for the extraction of organic pollutants from aqueous samples with similar principle extraction as the stir bar sorptive extraction (SBSE). In this study the SR was coupled with HPLC-DAD and employed for the extraction and quantification o...
