Abstract

ABSTRACT: This paper describes the development of a new micellar solid-phase microextraction fiber based on cetyltrimethylammonium bromide-templated mesoporous silica electrochemically assisted self-assembled on copper wire for sensitive determination of polycyclic aromatic hydrocarbons by HPLC. After optimization of experimental parameters, non-polar analytes of PAHs were successfully determined in water samples after microextraction by CTAB/MCM-41 copper fiber as micellar organic platform. The proposed method indicated good linearity in the range 0.01–82.5 µg L −1 and limits of detection in the range 3–46 ng L −1 . Relative standard deviations of the method were obtained in the range 3.1–8.3%.
