Název v původním jazyce

Identification of Prometon, Deisopropylprometon, and Hydroxyprometon in Groundwater by High Resolution Liquid Chromatography/Mass Spectrometry

Popis výsledku v původním jazyce

Prometon, a major soil sterilant, and its main transformation products, deisopropylprometon (N-2-isopropyl-6-methoxy-1,3,5-triazine-2,4-diamine) and hydroxyprometon (4,6-bis(isopropylamino)-1,3,5-triazin-2-ol), were identified as the dominant triazine herbicides in groundwater samples from 51 locations in Colorado, USA, over a two-year time period. They were concentrated from water by solid phase extraction and detected using an ultra-high pressure, liquid chromatography-quadrupole time of flight tandemmass spectrometry (UHPLC/QTOF-MS). The transformation products, deisopropylprometon and hydroxyprometon, were confirmed using MS-MS experiments. An original strategy was applied to form the degradation standards for deisopropylprometon and hydroxyprometon, which consisted of photo-degradation of prometon followed by MS-MS analysis. The concentration of prometon ranged from the detection limit of 3 ng . L-1 to 87 ng . L-1, hydroxyprometon ranged up to 50 ng . L-1, and deisopropylprometon
