Development of a Simple Integrative Carbon Nanomaterial Microextraction Method with GC‐MS for Assessing Pesticide Residues in Apples

Journal of Chemistry, Volume 2023, Issue 1, 2023., 2023
The present study describes an efficient analytical method for analyzing apple pesticide residues. This novel approach employs ultrasound‐assisted cleaning (UAC), solid‐phase microextraction (SPME), and gas chromatography/mass spectrometry (GC‐MS). A fiber coating with carbon nanomaterials (CNMs) was used for the extraction process.
