AI Technical Summary

Technical Problem

Existing technologies are insufficient for efficiently and accurately detecting the content of 2-aminothiazole in marine sediments, especially in areas with dense offshore wind farms, where human activity disturbances and complex matrices make conventional methods difficult to meet detection requirements.

Method used

Ultrasonic-assisted extraction combined with hexyl chloroformate derivatization and solid-phase extraction was employed, followed by detection by liquid chromatography-mass spectrometry. Extraction was performed using a mixed solution of water, acetonitrile, and pyridine. Pyridine was used to adjust the pH and act as an acid-binding agent in the derivatization reaction. The target compound was converted to N-(thiazol-2-yl)carbamate n-hexyl ester, which was then purified and detected using a C18 liquid chromatography column.

Benefits of technology

This study improved the recovery rate and detection sensitivity of 2-aminothiazole, lowered the detection limit, and enabled efficient and accurate detection of 2-aminothiazole in marine sediments.
