A Novel Application of Natural Peat for Solid-Phase Extraction of Pyrimethanil, Flumetralin, and Kresoxim-Methyl in Water Using Gas Chromatography-Mass Spectrometry
Figure 2
GC-MS (SIM mode) chromatograms of (a) typical water extract fortified at a concentration level of 0.1 g L−1; (b) water control sample; (c) standard mixture solution at a concentration level of 0.1 g L−1. The numbered peaks are as follows: (1) pyrimethanil (16.9 min); (2) flumetralin (18.1 min); (3) kresoxim-methyl (18.6 min). See Section 2 for details on the GC-MS system and operating conditions.
