Overview

Experimental study demonstrates sensitive trihalomethane detection in drinking water, indicating solid-phase microextraction suits routine water monitoring.

Key Points

  • To optimize headspace solid-phase microextraction coupled with gas chromatography and mass spectrometry detection for measuring trihalomethanes in drinking water.
  • Used a 75 μm carboxen/polydimethylsiloxane (75-CAR.PDMS) coated fiber for headspace solid-phase microextraction coupled to gas chromatography and mass spectrometry.
  • Optimized extraction parameters including sample volume, extraction duration and temperature, desorption duration and temperature, magnetic stirring, and sodium chloride addition.
  • Assessed analytical performance metrics such as linearity, reproducibility, and detection limits.
  • Achieved high analytical sensitivity with detection limits reaching the μg/L range for trihalomethanes.
  • Demonstrated good linearity and high reproducibility across optimized extraction conditions.
