Area of Science:

  • Environmental Chemistry
  • Analytical Chemistry

Background:

  • N-nitrosamines are a class of environmental contaminants.
  • Traditional methods for N-nitrosamine analysis are time-consuming.

Purpose of the Study:

  • To develop a rapid and selective method for extracting seven N-nitrosamine compounds from water.
  • To evaluate the performance of solid-phase microextraction (SPME) coupled with different gas chromatography detectors.

Main Methods:

  • Solid-phase microextraction (SPME) was employed for the extraction of N-nitrosamines.
  • Gas chromatography (GC) with nitrogen chemiluminescence detection (NCD), nitrogen-phosphorus detection (NPD), and chemical ionization mass spectrometry (CI-MS) were utilized for detection.

Main Results:

  • The developed SPME method achieved a total analysis time of 1.25 hours.
  • Method detection limits (MDLs) in the ng/L range were obtained across tested detectors.
  • Excellent extraction selectivity was demonstrated, particularly for N-nitrosodimethylamine (NDMA) in wastewater samples.

    • Conclusions:

    • The SPME method provides a fast and selective approach for N-nitrosamine analysis in water.
    • This technique is suitable for general surveys, wastewater monitoring, and laboratory studies like degradation kinetics.
