Online analysis of five organic ultraviolet filters in environmental water samples using magnetism-enhanced monolith-based in-tube solid phase microextraction coupled with high-performance liquid chromatography

摘要

Highlights?A new PIL-MCC/MNPs was fabrictaed.?The PIL-MCC/MNPs was used as extraction medium of ME-MB-IT/SPME.?The ME-MB-IT/SPME could extract organic UV filters effectively.?Online ME-MB/IT-SPME-HPLC/DAD system was developed for the analysis of UV filters.AbstractDue to the endocrine disrupting properties, organic UV filters have been a great risk for humans and other organisms. Therefore, development of accurate and effective analytical methods is needed for the determination of UV filters in environmental waters. In this work, a fast, sensitive and environmentally friendly method combining magnetism-enhanced monolith-based in-tube solid phase microextraction with high-performance liquid chromatography with diode array detection (DAD) (ME-MB-IT/SPME-HPLC-DAD) for the online analysis of five organic UV filters in environmental water samples was developed. To extract UV filters effectively, an ionic
