Optimization method for quantification of sunscreen organic ultraviolet filters in coastal sands

Résumé

Most organic UV filters are very lipophilic and some of them are difficult to quantify in the environment. This article describes a method optimization for quantification of these compounds in sand samples with diverse compositions. The standard additions method was used. The search for a unique HPLC method to analyze all these filters along with the search for optimal detection conditions are presented in detail. The best extraction solvent was methanol, and the best conditions for analysis and detection involved the use of an HPLC system equipped with a biphenyl column (2.6 µm, 150 x 4.6 mm) and an Orbitrap MS detector. We also demonstrated that sample freeze-drying can induce significant loss of some of the UV filters.
