A study to determine the feasibility of using 31P NMR for the analysis of organophosphorus insecticide residues in cole crops

It is not generally recognized that 31P NMR spectroscopy is now sensitive enough to be used for the analysis of organophosphorus insecticide residues without resorting to the extraction of large samples or the use of prolonged NMR acquisition times. The analysis of pesticides, such as disulfoton, di...

Zusammenfassung:It is not generally recognized that 31P NMR spectroscopy is now sensitive enough to be used for the analysis of organophosphorus insecticide residues without resorting to the extraction of large samples or the use of prolonged NMR acquisition times. The analysis of pesticides, such as disulfoton, diazinon, dimethoate, parathion, and azinphos-methyl, has been demonstrated to be feasible at 0.5 ppm on broccoli and cabbage
