Journal ArticleDOI
Determination of hydroxylated benzophenone UV filters in sea water samples by dispersive liquid-liquid microextraction followed by gas chromatography-mass spectrometry.
TL;DR: The recoveries obtained by using the proposed DLLME-GC-MS method evidenced the presence of matrix effects for some of the target analytes, and thereby the standard addition calibration method was employed.
